I am a cruiser of significant experience. I have sailed many days on Crystal, as well as having sailed on Seabourn, Holland America Line, Azamara Club Cruises, Norwegian Cruise Line, P&O Cruises, Royal Caribbean, Princess as well as the now defunct Transocean Tours' MS Marco Polo and Voyages of Discovery's much missed MV Discovery. I have sailed multiple times in the Mediterranean and Caribbean, as well as the Northwest Passage, Antarctica, South America, Asia, Alaska, Norway and the Baltics.
Whenever I do a review, I review the ship against what it A) is pertaining to be, and B) value versus the price paid. In this sense, a Crystal cruise may not receive five stars if the voyage did not meet my high expectations, whilst a 3 night Norwegian Cruise Line voyage may rate higher if my substantially lower expectations were exceeded.
In my opinion, the MSC Yacht Club product is the best value in luxury cruising. My wife and I are in our mid 20s, and we appreciated the fact that we had our own enclave aboard, where the crew quickly learnt our names and favourite drinks, but could at will descend into the melee of a mega-ship filled with energy, music, song and dance. The Yacht Club was in essence a haven (pun unintended), a quite, relaxing area, approximately the size of one the older Seabourn triplets, where it was easy to meet passengers and make friends, in a fashion that is usually impossible aboard a ship carrying several thousand passengers. One could then go and enjoy the entertainment and options available on the ship with said friends. The entertainment was of high quality, especially the Cirque de Soleil show. Every night a production show was presented, of which one can get tired of quite quickly, but they were of similar quality to shows I have seen on other mass-market lines. The overall ambiance of the vessel was international, which is something we really enjoyed about MSC, and the Meravilliga's interiors where nothing short of stunning. We did not try any eateries besides the Yacht Club restaurant and the buffet, so cannot comment on the quality of food in the rest of the ship.
