Dining: All 3 complimentary dining rooms were very crowded every night. Menu didn't change much over 7 days. They added a couple entrees each night. Sorry to find out Prime Rib was never served!
Entertainment: Theater shows were crowded, reservations were needed some nights. They have another venue with a dinner & show which of course was an extra fee. There were no house band(s) playing music for dancing and really no place to dance except on the aft deck outside. The Bliss Lounge was very small and not used much at all. Music was basically a DJ. I've been on smaller ships with 2 bands playing every night in different dance venues. There was a small lounge with rock bands which was very loud and crowded. Only entertainment bright spot was the 3 comedians and "dueling pianos" in the Headliners Comedy club.
Pools: No separate one for for adults, packed with kids every day.
As a solo cruiser, I liked the idea of the studio cabin. It's kind of cool, but It's still basically an inside cabin with no windows. The studio lounge is also a good idea for meeting other singles. Probably won't book a studio cabin again, even an obstructed view inside cabin would be better and not cost that much more.
