My Wife and I got back about 2 weeks ago now from our first trip to Europe. We did a Rick Steves' tour and stopped in Paris, Switzerland, Munich, Venice, Florence and Rome. Here are a few pics that I took, we had a blast!
Vatican
The Pantheon
Roman Colosseum
Switzerland
Notre Dame
Random tower in Paris
Venice
Wife and I on our way out of Florence
The Rialto bridge at ~6am. One of the major benefits of staying in Venice is being able to beat the MASSIVE amount of people that arrive via cruise ships. Early morning Venice is like having the city all to yourself. We had breakfast and coffee by ourselves on the Rialto [over the Grand Canal] two mornings.
Switzerland
The view from our balcony
We had dinner in this very cool 1243 wine cellar
Saint Chappelle [Paris] is just wall to wall stained glass
The Forum in Rome
Colosseum
