Cruised on the Norwegian Sun Eastern Caribbean Feb 26- Mar 5 2011. This was only our second cruise, first being NCL Spirit in 2009. We drove from Chicago to Port Canaveral. Boarding was very quick and easy. We took advantage of Casino at Sea boarding line, it was empty. Balcony cabin had plenty of room. Coffee maker in room. Minibar had room to store a couple of cans of Coke (we bring our own) , but it was not cold enough to do the job. Air conditioning in room was also borderline, had to keep drapes closed during the day when we weren't in room to keep sun from heating it up. Shower was very strong. Cabin attendant was excellent, as were all the crew we dealt with.
As previously noted in the other reviews of the Sun, the one glaring fault is the small size of the buffet on the Sun. The Spirit is about the same size as the Sun, but its buffet is twice the size. We avoided it and ate in the main dining rooms and snacked at the aft outdoor cafe. Service in the main dining rooms was first class. Wait staff is very attentive and professional.
The shows were good, specially the female singer-dancers. Many party functions were held in the Dazzles Disco, which I thought was way too small and jammed with furniture. The observation lounge was much bigger, but seemed to be under-utilized. The Spirit held its larger events in the observation lounge, the Sun should follow suite.
