This was our first trip on a Solstice Class ship, and the reviews do not do it justice. Although the ship was full, we never felt a sense of 'crowd'. While there may have not always been poolside chaises available, the deck above the pool as well as some of the 'hidden areas' always had plentiful options.
We tried all of the specialty restaurants, and found them to be worthy of the extra cost -- we especially enjoyed the old world elegance of Murano, and found both the creativity and presentation of Qsine to be memorable. Dinners in the main dining room were outstanding, and the service and care taken by our servers (Sergio and Olga) made it a pleasure.
Our stateroom was ample, and the storage facilities worked perfectly for 2 people who tend to overpack. The replacement of a shower curtain with a door made a huge difference, and bathing never felt cramped.
The only negative comments that I have deal with the Persian Garden and the Aqua Spa Cafe. The Persian Garden we enjoyed on a Millenium Class ship was far superior to the one on the Solstice class. This Persian Garden seemed more like an assembly line, and did not come anywhere near matching the tranquil ambience we had previously experienced. We went one time, and cancelled for the remainder of the cruise. The Aqua Spa Cafe provided light, healthy, and tasty food - however, the number of people who wound up using the too few table for card playing, reading, and general non-dining activities made it difficult to find a place to sit an enjoy the meal. Celebrity should occasionally 'police' the area, to insure that once people are done eating, they move to allow other diners access to the tables.
As this was our 2nd cruise on Celebrity, it reinforced the positive overall experience of our prior cruise (also Transatlantic). Every employee that we encountered went out of their way to make sure that the trip was pleasurable, and they seemed to possess a genuine enthusiasm and positivism that made you want to smile. It became so accepted to us, that when we checked into a hotel in London at the end of the cruise for 3 nights, the difference in attitude, service levels, and caring was the polar opposite.
We are already looking at our next Celebrity cruise for next year!
