kokopops: I think the CC is well worth it. We've always stayed in CC or Sky Suite, but the last cruise in February didn't and we were disapointed! It's fun to get the champagne, fresh fruit (every day) fresh flowers twice on your cruise (that last), colored towels (as apposed to the white ones), leather key-card holder, priority embark / disembark, larger robes
, canopes (appetizers) every day around 4 PM-oh yeah! Also after your 5th cruise, your CC can be upgraded from a C2 to a C1, at no additional cost. Basically, it's just a better choice of cabins.
Phyllis: I had the same question about our stateroom number 9038 on our upcoming cruise in September. I put the following into Google: "cabin 9038 celebrity constellation" and was surprised at what I found! There was information on this site, as well as cruisecritics.com which was helpful to us.
