I went with my Boyfriend in May 2003 and we had a fantastic time. It wasn't a honeymoon (thankfully as we are now broken up) but we had a really good time. The time you are going is off season so it shouldn't be crazy crowded and you can arrange a lot of special things like:
1- romance escape package (you can book palo b4 you board plus couples massage).
2- have you stateroom decorated or bring something for the door
3- have Shirley at the Perfect Gift send a nice romantic honeymoon basket
4- arrange romantic and fun excursions.
Basically post wedding you are going to want to be pampered and who does it better than Disney!
