I'm one half of a couple in our early 30s (no kids). We wanted a last-minute get-away, something quite that we didn't have to plan or stress about, so we tried our first cruise together. I think Celebrity was the right choice- we had a lovely time. Being inexperienced cruisers, we asked many of the cruising veterans what their favorite line was. They all liked Celebrity, with one exception (an older lady preferred the floor plans of princess). We loved it.
Boarding: We were instantly liking it upon boarding - we were greeted with some tasty champagne, and were impressed with how stylish the ship was, very sophisticated. We were swept up to the suite line even though we just had an inside stateroom (with no lines) because we were on deck 11 (the penthouse deck).
Ship Overall: Very chic. Loved the art and the sleek feel. Overall very clean. The pools were nice, the Solarium was adult-only (except, on a few occasions I saw kids sneaking in since it was right next to the general pool). Lots to see, the ship has a ton of small alcoves and areas to sit and enjoy the scenery.
Solstice 1532 - inside stateroom with a lot of great benefits for an inside stateroom! Just walk up a flight of stairs and you're in the spa/adult pool area. It's on the suite deck, so it's quite. And you're down a hall that branches off, last one on the line, so it's extra quite. I think the floor plan was nice because it was longways, plenty of walking room. I think our steward was extra good since he was also the one who serviced the suites. Another bonus about being on the penthouse deck: we waited in zero lines while embarking! We were routed to the suites area, even though we're just paying for a lowly inside stateroom. Bed was very nice.
Because we're under the spa, it's very quite above us at night since it's closed.
I think there's an ice maker near by because we could occasionally hear it dump. It's forward, so we could feel the motion of the ocean a few times, but it was actually kind of nice, it lulled us to sleep. We did need to have the AC checked up on, but the problem seemed to be fixed quickly. I'd for sure book this room again.
