When I traveled to England we stayed in a hostel and it still cost us an arm and a leg and NEVER slept!! If you are going you might as well spend the cash and get a cheap hotel b/c the hostel was horrible!
When visiting europe bring a backpacking back pack so you are able to see as much as you want to see in europe.
1. If you have friends of friends in a place you've never been before... make sure they become your friends.
I always keep a little of the foreign currency from every country I've been to: you never know when you'll need it in a flash!
Always brush your teeth with bottled water
ALWAYS CARRY AN EXTRA LUGGAGE! You always end up coming with more than what you brought.
The MOST important thing while traveling is not planning everything.. leave something for adventure.. and thoes will be the best times..
For the best advice on what to see or where to stay or even what foods and driinks to try go to a local pub or coffeeshop and caht with the locals...
When I visit...Europe I always sleep with my passport.
