Just returned from 7 nights on the Celebrity Constellation. Ports of Call included Dominica, Aruba and Curacao. The cruise dates included Christmas and Hanukkah - we returned to San Juan on New Years Eve.
This is my 3rd cruise. In the past we've cruised with Radisson and everyone said we we would be disappointed by any other cruise line. That was not the case. While there was certainly a difference in the experience, I was delighted with our Celebrity Cruise.
The Pros: The embarkation and disembarkation were easy and efficient. The cabin was roomy enough for 3 adults and all our luggage. (We had a room with a balcony on deck 9). The ship was lovely and kept spotless.
