I'm a pretty big fan of Rick Steves. He really does go to all of the places he recommends and finds a few off the beaten paths of places to visit. What I have noticed is that he does his homework.
Why not go for trusting from someone who knows best.
Forget the book - watch the stunning DVD of Rick Steves- Best of Travels in Europe. This DVD set includes (British Isles/France/Spain & Portugal/Germany, Austria & Switzerland/Italy/Greece, Turkey, Israel & Egypt).
I'm sure you'll be ready for your trip to Europe once you watch this. It certainly got me ready!
