Pinnacle Grill and Tamarind are amazing, both in quality of food and service.
Main dining room and buffet also had great service, but the food was hit or miss (which is to be expected for mass production). Also to be expected: the buffet area can be a madhouse at times and finding a table for larger groups can be a challenge. The main dining room was just the opposite: most table around ours were empty on the two nights we ate there.
Billboard Onboard was great fun, especially the request shows later in the evening. It was great to see everyone sing along and have a great time with the two performers.
Only caught the illusionist on the Mainstage and was surprised at how great his show was.
Didn't spend time at BB King, America's Test Kitchen, or Lincoln Center Stage, but did walk by during performances and all appeared to have standing-room only (Lincoln Center Stage sounded incredible, so sorry to have missed that performance).
Like any cruise, spa treatments on board aren't cheap, even when they offer special discounts. What's worse is the up-sell on products after every spa appointment. However, we did make great use of the "discounted" spa pass that allowed daily access into hydro-pool, saunas, and ceramic-heated loungers (for $149 per cabin with two passengers).
Our cabin (7080) was a little larger than most Signature Suites since it's located right were the ship juts back out from the center. The extra space extends the cabin quite a bit and might have been better suited for additional square footage on the balcony, but it's also a great spot to store empty luggage.
Bed was comfortable and AC/heat both worked well.
Hardly heard any hallway noise in the evenings, nor anyone in the cabins next door or above.
Cabin was always attended to quickly in the mornings and in the evenings for turn-down service.
