OMG, it was great.
The Navigator is terrific, the service was excellent, the food was really really really good. We used the Cruise line to book our air and transfers and were pleased. One stop from Baltimore to Miami, in Atlanta and a direct flight on the way home. We got to Miami airport by noon and were having lunch on the ship at about 1:45. Embarkation and Debarkation were simple smooth and hassle free.
Having only cruised once before on HAL's Westerdam last spring break, that is my only point of reference. It was miles better in almost all categories. You can sail on the Navigator with no cares or worries.
