This is our first time to sail with Celebrity and we found the Solstice to be a good quality boat. The food was well above average and two of the specialty restaurants, Murano, and Silk Harvest were of excellent quality.
The cleanliness of the ship was very good and the staffs attention to sanitization was omni present. We sailed in the concierge class which for a few more dollars offer a somewhat faster embarkation and few extra perks for the room.
Room steward services were seamless and polite and our person went out of the way to help us with a few things we either lost intransit or forgot to pack.
A little on the crampted side but manageable. One of the larger shipboard baths I've seen.
