Firstly, I will start with my opinion on the ship. Very beautiful, and in my opinion, well designed. The cabins are smaller (we had a deluxe balcony) than on say, Independence of the seas, which is a problem as we had 2 girls with us, aged 10 and 11. You had to be very efficient with where you put things, fine for 2 people I would say (even though my parents said they didn't have enough room, but they are used to larger cabins also). I was concerned that my girls would not have enough to do. The clubs were fantastic, my girls don't really like the clubs much, but it was hard to get them out at times! The staff were very friendly and happy for us to pop in anytime to check on them. They get trips to the bridge and backstage tours for example (older ensign groups upwards, not sure about the little ones...). Also I liked that the clubs take the children to see the production shows (I have trouble getting my girls to the theatre to see the shows, but they were more than happy to go with their friends and all supervised closely by staff). There were 80 children in total on board, not a lot considering it was half term. We were in room 9229 and the first night we had a creaky roof, when I reported this, it was sorted immediately with follow ups from the maintenance team. Nothing was too much trouble, it you wanted anything, you just asked and you got! For example, I had an excellent Fillet mignon one night and asked for my dad to have one the next night, which was sorted. If you wanted anything in the main dining room and it wasn't on the menu, if you asked for it, the next night you can have it, they have a whole section for special orders. Our waitresses Jelena and Karolina were really attentive and loved our girls and Kevan also helped out on the nights that Karolina was poorly, but even then, the service was seamless. We felt no need to try the other restaurants (we did have a look at them and they looked fantastic and was temped by Murano for a special meal). Only tried room service once and within 10 mins the breakfast for my daughter arrived. The officers on the ship all spoke to you and were very visual. Sarah in the entertainment team was fab and was great fun, hosting lots of the events on board. Some have said there wasn't enough to do, well I thought there was a lot for all ages and tastes if you wanted it. As for the music, there was lots of variety all over the ship, I loved to listen to the different types of music and was nice that it was during the day as well as the evening. All the staff spoke to you and you felt that they meant it. They were very good with my girls, being very patient and helping them out with items on the 'scavenger hunts' from the club. When we did the family hunt, one of the staff even offered to go to another kitchen 2 decks down to get a banana for us! Lots of little extra things that I noticed that set celebrity above Royal Caribbean and P&O, iced towels when arriving back from onshore and a nice welcome, better service and lots more room (even though our cruise sailed full). Staff often remembered your name in the bars and what you had to drink.
As for the shows, I liked the production shows (especially Eclipse, so don't miss that one), some of the other shows weren't to my taste but then you have to cater for all age groups. I would say the average age of passengers was about 55-60 but there were other families like us and younger peeps about too. The theatre was nice and very comfortable seats.
Didn't have any spa treatments, too expensive, but I knew this, as I have been on american ships before. Used the gym and the jogging track.
We did have a creaky roof, that was sorted straight away and stopped. You could also hear a lot of toilet flushing, think our cabin was near a toilet flushing highway! More closet space would be better, very tight for 2 adults and 2 children (but fine for 2 adults!). Lovely cabin though, would not let the above put me off but next time have booked a 1A on the hump (bigger balcony).
