Shdw...listen to Enfuego and Kermit
You won't be sorry and you will remember it for the rest of your life and do not do any gambling when you are on this trip...but if you are in Europe, attend a soccer game or two..
Nothing quite like riding the London tube to Upton Park for a West Ham United soccer game with their crazy fans. It's an experience.
Italy, everyone should visit Rome at some point in their life. Venice and Florence are beautiful as well. So much to see and do you will never want the honeymoon to come to an end. Paris is incredible as well.
