Just way to many people and kids.  First time on a 4200 person ship.  Excursions were great, food was great.  Should be able to get Vibe at time of purchase.  Only local people can get there early enough to get it at boarding.  If you have never been on ship 4200 people it is a new experience.  Way to many people and kids to deal with.  Pools are the same size as smaller ships,  and really crowed.  Cabins are much smaller than usual. 

Boat and crew clean and always responsive to guests. Medical staff was great and very professional as were all service related personnel on board.  the upscale restaurants were very good to excellent, in both service and taste.  We never went to main dining for dinor.   I would personally not want to visit Roatan again.  The snorkel and catamaran ride were terrible.  Bad reef and short ride back to the dock.  City and surrounding areas are not safe or sanitary looking.   Belize should be left off if only for the problem using tenders and condition of the local surroundings.  Costa Maya great must see Mayan ruins.  Cozumel has really become a great destination in last two years.  All new buildings and restaurants and things to do.
