After multiple trips, tons of in-depth personal research in places like Rome, London, and Paris, and years as a Certified Travel Expert℠ specializing in custom-designed itineraries, here’s something I’m confident about: I definitely know how to plan a trip to Europe.
From choosing a destination to booking lodging and transportation to ensuring all your documents are in order, there’s a lot to keep track of.
I want to give you the inside track on my planning process so you can enjoy your trip with the least stress possible. Because there’s nothing like that amazing moment when your plane takes off and you are officially on vacation (it’s one of my favorite feelings!) — and it’s even better when you know everything’s in order.
So, the countdown is on. Are you ready?

The “biggies”: taking care of non-negotiable and high-demand items

This is when you want to choose your destination(s) and prepare an itinerary outline: which country (or countries) you want to visit, which cities are on your must-see/stay list, and the pace at which you’d like to travel.
This third consideration (pace) is incredibly important when you’re approaching how to plan a trip to Europe and can really affect the quality and restfulness of your trip. Sometimes people assume it’s best to see as much as possible and fill every spare minute — but in my experience, the ideal itinerary will find a nice balance between seeing and savoring.
So ask yourself: Are you someone who likes to be in a different place every night on a whirlwind tour? Or do you prefer to have the time to linger?
Once you know your destination(s), it’s time to book your flight to and from Europe.
For any high-demand accommodations, tours, or events that are likely to get booked out early, now is the time to reserve your spots.
And don’t forget to double- (and triple-) check your passport and any other essential travel documents. Remember: your passport has to be valid for six months after your return date.
Cassie’s Tip: Did you know that September/October is usually when early bird fares are released for the following year? So if it works with your general timeline, even if it’s a bit more than 9 months out, this can be a great time to scout the best deals on flights.

In-country essentials

If you’re planning on visiting more than one country, this is the time to book inter-Europe flights.
By this time, you’ve prioritized your sightseeing list and should know what your day-to-day plans will be: museums, tours, local attractions, historical sites, day trips, etc.
This is also when you should finalize your accommodations and book any long-distance train tickets that you’ll need for traveling in-country or between countries. Train travel across Europe is easy, convenient, fast, lovely, and generally quite organized.
For example, the train from London to Paris is less than 2.5 hours, with no airport hassles or transfers. It’s very easy to have a “home base” city and then plan day trips out from there — even to other countries!
Cassie’s Tip: This is for grown-ups, too, but especially if you are traveling with kids — don’t overbook your days. Give yourself LOTS of room to rest. People often think they can cram in four sights in a day — but in reality, one or two things per day is plenty. Make time for relaxed meals, time in parks, walks to stretch your legs, fresh air. I promise: it will triple your enjoyment.

Local transport and finalizing lodging

If there are any places you haven’t secured a hotel, or if you’ve tweaked your itinerary in any way — this is the perfect time to tie up any loose ends.
Also, local transport like rail lines usually allow booking 90 days in advance. So this is when you should be researching your sightseeing plans, determining different station stops, and getting the tickets you’ll need.
Cassie’s Tip: Part of knowing how to plan a trip to Europe is figuring all these details out, and this phase of planning can get overwhelming very quickly — especially if you’re new to your location’s transportation systems or are unfamiliar with a city. Guidebooks can help, but if you need expert input, don’t hesitate to call on someone who knows these systems inside and out. I can save you dozens of hours of confusion, stress, and meandering the Internet!

Almost there!

Unless a certain tour is in very high demand (think: Versailles Bike Tour), two months should be enough time to secure your spot on the sightseeing tour of your choice.
Does your itinerary call for an airport transfer? Now is a good time to book your private driver to/from the airport.

Final details — oh, and don’t forget the food!

If you have a folder with all the info you’ll need, this is a great time to get well and truly organized.
Make sure all reservations are confirmed.
Print out — or digitally have a place with easy access — documents with any special instructions you might need. This can include contact info, driving directions, check-in guidelines, or important reminders.
If you have a favorite travel app or guide that you want to upload to your smartphone, this is the time to get that all set up. Montage Travel uses an app where clients can easily access their full itinerary details, entry tickets, GPS maps, documents, and more.
And — maybe the most important of all! — make and finalize any dinner reservations. A well-fed traveler is a happy traveler!
