We celebrated our 30th anniversary on a wonderful cruise. We were booked in Aqua Class which allowed us access to Blu Restaurant, the Persian Garden Spa, and offered us several additional amenities in our room (including bottled water, raspberry tea, daily afternoon canap's, and a few other room items). There may have been other perks - but it was all very nice. We also bought a Classic Drinks package which was VERY cost effective - it allowed us free drinks up to $8/glass - and I believe a 20% discount on bottles of wine.
Our favorite spots on the ship were: our balcony, the Solarium (for afternoon napping - very quiet), the Sunset Bar, the Lawn Grill (specialty restaurant and private alcoves), and the fitness center. We generally got breakfast at the Aqua Cafe - with an added hash brown patty from the Ocean View Cafe.
The fitness center was usually full in the morning - but still easy enough to find a cardio machine or work in on some weights. The classes offered were great - especially the FlyWheel (beware, though - it's tough!). Whatever the workout was, it helped counteract some of the delicious food we had on board.
Great location! Far enough away from elevator, but not much traffic down hallway. Easy walk up the stairs to Spa/Fitness area and/or Pools, Solarium, Cafe's. We were just below the spa so it was never noisy above us - and I think you could smell some of the calming aromas from the spa from our balcony! We always seemed to be on the side for sunset views too.
