We went as a family of 8 with ages ranging from 13 to 93. Our third cruise. Had been on Princess and Carnival before.
Overall, it is an amazing ship. Well designed. Very stable. It is huge. The big main walking promenade and the 'central park' are great ideas. There is even a ice skating rink.
The staff were excellent, as were the main shows. They had a full production of CATS.
Cabana Rental. Expensive yes but for a group of 8, worth it. You get a nice beach close to food. Has a nice cabana with shade that can accommodate a lot of people even though they say only 4. The attendant brings drinks and always available. Nice beach. View of the zipliners zipping over your head. The water is swimmable but you really ought to have water shoes.
