We didn't have much of a honey moon (starving college students, spent the weekend at a Maine beach resort... in January, lol).
For our 10th, I booked us on a Caribbean cruise. DH (and the kids) didn't know til we got to Miami. It was a stressful secret, but we had a great time. (Plus kids' club on the ship= we got some alone time in the family vacation. Best of both worlds!)
