4. Day trips are a great idea:
There are small cities and towns in Europe that are absolutely worth discovering. Salzburg is a 2 hour drive from Munich, and Karlovy Vary is a short ride from Prague as well. Day trips are easy and affordable, and you don't have to cart your luggage everywhere. Just get on a train and spend the day in a different city. While you get there, enjoy the breathtaking lush green meadows, rivers, lakes and bridges that come your way. Sure, it's not nearly enough. Pick 2 cities or 3 at best (depending on the duration of your trip) within close proximity to one another.
5. Hop-on Hop-off buses:
Little is said in praise of these HoHo buses! Every major tourist town/city has a Hop-on Hop-off bus service that's affordable, convenient and well-located. These buses have dedicated stops around the city, allowing you to get on and off the bus at your convenience. Every few minutes another bus comes along and you can board this to your next stop. You can get off anywhere and spend as much time as you like, then get back on the next bus. Tickets can be purchased at railway stations in most cities and you can board the bus right away. I bought mine for 16 Euros in Salzburg, and it came with a map of the city as well as headphones to plug into the seat pockets for information on each stop. It might have just been the most useful purchase of my entire trip. The HoHo bus in each city operates differently- remember to check that out and pick one basis your preference. They sometimes have different routes and you can pick the one that you prefer based on their designated stop locations. These HoHo buses also sometimes have 3 day passes that are perfect for anyone who plans to do a lot of exploring over the next couple of days.
6. Trains to different cities:
The closer you buy your tickets to your travel date, the more expensive they become. Reserving seats costs additional Euros. If you aren't traveling during peak season, or a busy sector, go ahead and book your tickets without a reservation. It could save you serious bucks! Pick early morning trains so you can make the most of your day. Nobody wants to waste precious Europe hours! Goeuro.com is a quick and reliable place to book train tickets, aside from being easy to understand.
