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.
