Thanks for the input. We were on Infinity in 2001 in March and the program was in full swing then (although our daughter was too young to participate). However, based on comments I've seen on this site, before I booked I called Celebrity just to be sure. They told me that their children's program is year round but that activities vary depending on how many children are on board. I sure hope I haven't been misled....
I was hoping to hear from other families that were on our cruise so that we could talk up the other kids w/ our daughter ahead of time. She was on two Carnival cruises last year and did not like the children's program. Because she's normally so adaptable, we think that it was likely just lack of familiarity and hope that we can talk w/ other families on our cruise ahead of time so she can look forward to meeting their kids.
