When it comes to cruising I've found there is no substitute for a good, local cruise specialist. This is what how my specialist explained the Celebrity change to me:

All 1A staterooms will no longer have the Concierge Class after April 17th on all sailings. Celebrity has moved some 1A staterooms to a CC category. If you book a 1A which will sail after 4/17/04, you will not receive the priority check-in, concierge service, robes, flowers etc. It is just a balcony stateroom.
