We caught Ovation of the Seas from Singapore to Sydney in November. Ovation of the Seas is a
BIG ship and from my perspective has a lot of wasted space. For the size of the ship there is nowhere that you can watch a decent cabaret show as, other than the theatre, there is nowhere that has enough seats. The Music Hall at the Bow end and Two70 at the other are very nice but cannot handle the capacity crowds when there is a good show on.
The elevators have a mind of their own though that is a common comment about many ships.
The specialty restaurants could be bought as a package and that was pretty good value. Wonderland, Chops Grill and The Chefs Table were all very good. Jamie's Italian Restaurant is overrated IMHO. The package also gives 40% off wines at all those dinners.
The regular restaurants are OK but do not compare the the restaurants on the Princess ships. There are also various other smaller eateries and a Bionic Bar.
Cabins/staterooms are about standard for a ship with slightly larger than average bathrooms. I'm not sure where the small beds comment came from above but I would have said they were average though no where near as comfortable as the new beds on the Princess ships.
On deck 15 there is a walking/running track and there was a walk with a ships officer every sea morning. On our cruise it was always the Hotel Manager (from the Gold Coast) and he was great value.
Personally I prefer the centre Atrium setup of the Princess ships but that's a very individual thing and very subjective.
I've added a couple of photos comparing the central mall on Ovation of the Seas with the Atrium on Majestic Princess. (These are both the newest ships in each fleet)

Ovation of the Seas centre mall.

Majestic Princess Atrium
As a comparison:
Ovation of the Seas is 167,800 tonnes and 4905 pax & 1500 crew. (3.27 pax per crew member)
Majestic princess is 143,700 tonnes and 3560 pax & 1346 crew. (2.64 pax per crew member)
