My husband and I are on the 1/20 Wonder cruise!! How exciting for you!! When is your wedding on Castaway Cay? (we won't gawk, I promise!!) We'll be too busy on Serenity Bay - the adult beach. I'm really looking forward to this - we were on a 3 day Wonder cruise last Feb and it'll be nice to have the extra day.
BTW, if you want LOTS of info. and an active DCL cruise board, check out www.disboards.com and go to the Cruise forum. But beware - many of these people are Disney fanatics and are really into the cruises - lol!
