Really enjoyed the Mariner of the Seas. Loved the fitness center. The staff was friendly and we had a good stateroom attendant, waiter and asst waiter.
The food was good for the most part although the desserts were rather bland. We usually stuck with the sugar-free desserts then as they seemed to taste better than the regular desserts. Wasn't too impressed with Cafe Promenade...except the fruit salad was good.
My son enjoyed the teen club and made a lot of friends.
Cabin 6502 - nice cabin..good size. Mediterranean was pretty calm so we were not seasick at all. Only 4 floors below the fitness center. Food (dining room, etc) are in the AFT section so it is a good walk to get there.
