Have an idea of sites you want to visit and things you want to do during your trip. Do some research on travel blogs and communities. You should ask friends and family who have traveled before about places they enjoyed the most. Read through site-specific guide books like Lonely Planet, Let's Go, Rough Guide, Rick Steves, or Frommers.
Book all travel far in advance. However, do not book anything until after the first week of classes. You may find there are NYU-sponsored trips already in place.
Things to remember about discount airlines:
Lists all your train options and information about the trains for all the different European countries.
If you are planning on traveling (especially after your semester) you may find that Eurail is the best option. It is a train pass that gives you train travel within 18 European Countries. Not only is it a cheap, convenient way to travel around Europe, but also many Euro trains are super comfy! Buy your tickets in the US as they are more expensive in Europe.
For travel within France and throughout Europe, you may be interested in purchasing a ticket through Eurolines.
Busabout is designed for back-packers which makes it a great way to meet people, and a cheap way to get around—it may be more appropriate if you plan to do more traveling during the summer.
I went to Amsterdam, London, Belgium, and Madrid. I traveled to all the cities by train except for Madrid, which I flew to. I made all of my travel plans online. I loved Belgium. I went during Easter, so we went to the well- known chocolate stores and saw their amazing displays. I had the best time going to places off the beaten track or finding good restaurants.
