We did this cruise (12/12) last year, and will be returning in 2005!
As for weather, we were on the beach in Nassau and at CC, and we all went in the water! That means it was warm, because we are from Vegas, and I won't go in if it is cold. My kids, OTOH, would break through a layer of ice to go swimming it they had to.
HOWEVER, the last night of the cruise, and the entire following week, were cold and wet, so it is totally a crapshoot!
This year, we are travelling with my sister and her DH. Our DD will be 11, and our boys will be 9 & 7. They don't know about the cruise yet, because we are cruising this summer, and don't want to spoil it.
Wonder if anybody else is on this ship?? We have connecting cat 9's. We LOVED deck 2 last year, but had cat 10's.
