10 Trip Planning Mistakes That Cost You Time and Money
A travel mistake is frustrating. A travel mistake that costs you time or money? That one stings.
Some mistakes are obvious. (Quick reminder: check your passport expiration date.) The sneaky ones are different. They feel perfectly reasonable when you make them. Then they quietly make your trip harder than it needs to be.
I'm Cyndi Smith, a travel advisor based in Overland Park, Kansas, and most of the trips I plan are river cruises, small-ship voyages, and custom itineraries in Europe. These are the mistakes I see most often, and how to sidestep them.
Tips for before you book
1. Booking basic economy to save a little
That lower fare is tempting. But basic economy usually means no changes or refunds, no seat selection until check-in, and boarding last. On most US airlines, if your plans change, you typically lose what you paid.
On a nine-hour overnight flight to Europe, that can also mean you and your travel partner sitting rows apart.
The fix: Compare the full cost, not just the fare. Once you add a seat, a bag, and the value of flexibility, the gap often shrinks to almost nothing. If you are traveling solo or your plans are 100% locked in, it be worth it. For a big trip, a little more flexiblity and fewer restrictions will be worth a lot. If you need a checked bag, a specific seat or need any changes to your itinerary, any cost savings you had will be gone.
2. Choosing nonrefundable hotel rooms by default
Nonrefundable rates can look like an easy win. But if your flight changes, someone gets sick, or your plans shift, that money is usually gone.
The fix: Book flexible rates unless the savings are big enough to outweigh the risk. Sometimes they are, and that's a perfectly smart choice. I'll show you both side by side so you can decide.
3. Comparing cruises by price alone
Two cruises can look hundreds of dollars apart on paper. But one might include drinks, excursions, Wi-Fi, gratuities, and transfers, while the other charges for every one of them.
The fix: Compare what's included, not just the fare. I line up the real numbers so you can see exactly what you're paying for. (More on this in the true value behind a river cruise price tag.)
4. Trying to see everything
Five cities in ten days sounds amazing on paper. In real life, every move means packing, checking out, catching a train, and checking in again. Suddenly half your trip is logistics.
The fix: Pick fewer home bases and stay longer. Take easy day trips from there. You'll see more, not less. Just because ChatGPT says you can visit that may cities in one trip, does not make it a good idea.
5. Skipping travel insurance
It's easy to think, "We're healthy. We'll be fine." Most of the time, you will be. But trips get interrupted for all kinds of reasons: a family emergency, a fall a week before departure, a missed connection.
Many people also don't realize their health insurance may cover very little once they leave the country. Original Medicare generally doesn't cover care abroad. And medical transport home can cost more than the trip itself.
The fix: Look at coverage when you book, not right before you leave. Some of the most valuable benefits, like coverage for pre-existing conditions, are often only available if you buy within a short window after your deposit. I'll walk you through what each option actually covers.
Getting there
6. Booking a connection that's too short
An airline will happily sell you a 60-minute or less connection. That doesn't mean it's a relaxed one.
This matters most on the way home. If you connect inside Europe to a flight back to the US, say Rome to Frankfurt to Chicago, you go through passport control at your connecting airport, because that's where you leave Europe. Add security, long walks between terminals, and a late first flight, and it gets tight fast.
Europe has also rolled out a new digital entry and exit system that registers visitors at the border. It's still settling in, and lines at some airports have been longer as a result.
The fix: Give yourself breathing room, especially when you're leaving Europe. I aim for at least two hours on those inter EU connections before a U.S destination, expecially at more at busy hubs like Paris or in Frankfurt (the worst for long lines at passport control when connecting to US bound flight). And when I can, I'd rather book a nonstop or an earlier first flight than squeeze a connection.
7. Arriving the day your cruise leaves
It saves a hotel night, so it feels smart. But one delayed flight and you're watching your ship leave without you.
The fix: Arrive at least a day early. You'll get over jet lag, explore a beautiful city, and board relaxed. I build your flights and pre-cruise night right into your plan so it all fits together.
8. Forgetting the entry details
Many European countries want your passport valid at least three months past the day you leave, and I recommend six to be safe. Europe is also preparing a new online travel authorization for US visitors called ETIAS. It isn't required yet, but it's coming.
The fix: Check your passport now, not the week before. I keep an eye on entry rules for my clients and let you know if anything changes before your trip.

Money on the ground
9. Paying in dollars instead of euros
At a restaurant, a shop, or an ATM in Europe, you'll often be asked: "Would you like to pay in dollars or euros?" Dollars sounds easier. It almost always costs you more.
When you choose dollars, the merchant does the conversion at their own exchange rate, which usually carries a markup. One study found that markup averages around 5% across Europe. Even a card with no foreign transaction fees won't protect you from it.
The fix: Always choose euros (or the local currency). Let your own card handle the conversion. Same rule at the ATM: decline the conversion offer.
10. Relying on one card, and no cash
This one happened to me. On a recent trip, one of my bank cards simply would not work in the ATMs. No warning, no explanation. I was glad I had another card with me.
The fix: Bring at least two cards that can pull cash, ideally from different banks, and keep them in different places. Check with your bank before you go about travel alerts and foreign ATM fees.
And pull out some euros early in your trip. Set aside what you'll need for gratuities, like tour guides, drivers, and housekeeping, before you need it. Otherwise you end up on a wild goose chase trying to find an ATM or break a big bill just to say thank you.
It's such a small thing, but it makes a difference. That's why I include tip envelopes in my clients' trip packages. You arrive ready, and saying thank you is easy.
Bonus: Locking in dates before looking at the calendar
Shifting your trip by even a week or two can mean fewer crowds, better availability, and a better price, often with no difference in the experience.
The fix: Think flexible before you think final. If you have any wiggle room, let's use it. (My 18 month planning strategy shows how far ahead the best options go.)
Tailor Made Takeaway
None of these are big, dramatic mistakes. That's exactly why they're easy to make. But a little preparation turns "oh no" moments into "no problem" moments.
That's what I do for my clients. I look at the whole picture, plan for the bumps, and make sure you're ready for whatever the trip brings, because it's travel so it's not if a problem will happen but more like, when a problem is likely to happen. All you have to do is get excited for the trip!
Frequently Asked Questions
Should I pay in euros or dollars when traveling in Europe? Euros, every time. When you choose dollars, the shop or ATM converts the price at its own rate, which usually costs more. Let your card do the conversion instead.
How long should my layover be when connecting in Europe to fly home? I recommend at least two hours, and more at large hubs like Frankfurt or Paris. You'll clear passport control at your connecting airport before your flight to the US.
Do I need travel insurance for a trip to Europe? It isn't required for most US travelers, but I strongly recommend it. Your health insurance may cover very little abroad (if anything at all), and original Medicare generally doesn't cover care outside the US.
How much cash should I bring to Europe? Cards work almost everywhere, so you don't need a lot. Keep enough euros for tips, cafés, and small shops, and refill at a bank ATM as needed.
Do you tip in Europe? Tipping isn't expected the way it is at home, and customs vary by country. A few euros for a great guide or driver, and rounding up at restaurants, is a kind thank you.
How long does my passport need to be valid to travel to Europe? At least 6 months beyond the day you plan to leave the Schengen area. I suggest six months to be safe.
Do Americans need ETIAS to visit Europe? Not yet. ETIAS hasn't launched (delayed again until 2027). The start date has moved several times. I keep my clients posted so nobody gets caught off guard.
