My daughter and I just sailed her over the New Year's Holiday. We enjoyed it. I thought the restaurants were really just ok, but the entertainment was much better than an our prior NCL and Carnival cruises. If you want to go to Second City, make sure to make reservations. We also made reservations for Rock of Ages, but I don't think the show was full. Burn the Floor, Howl at the Moon, and the blues combo (sorry, forgot their name, but I think both the performers in the blues venue and Howl at the Moon have changed now) were all excellent. Apparently I have been remiss in my 22 year old's musical education, because after we were in the blues venue for a few songs, she said, "this is great! How come i never heard this stuff before?"
The buffet can be crowded, but we always were able to find a seat when we went, and if you are traveling with kids, there is such a wide variety of food that even picky eaters will find something to eat. After a couple of days, we discovered the lunch buffets in Moderno. They were smaller, but much more relaxed, and always had a theme, such as Mexican or German.
The ship is very large, and our sailing was full, but yours may not be. The only time it FELT crowded to us was the last sea day, because it was cold and everyone was inside. We had unseasonably warm weather when we left New York. Oh, and catching a tender was a pain, but in Bermuda I don't know if you will have that problem. The pools were probably crowded, but we didn't hang out there. We would just go up a deck or two to avoid the chair hogs and find a private spot. There is also an adults only area, spice H2O, but we only went once or twice, because it was pretty windy when the ship was moving.nThere is also a pay private area, but since it was outdoors and December, we did not even consider paying for that. Those passes I think you have to buy onboard, so you have to try to board early.
You might want to consider a spa pass, especially since you are going in October, which we did, and used a lot. It doesn't get you spa services, but it gets you access to an area with heated stone loungers in front of floor to ceiling windows, a thalassotherapy pool, hot tub, salt room, rain showers, steam room, and sauna. The stone loungers can be hard to snag, so we went early in the morning for a while and then returned later at night. I think the spa was closed one evening of the cruise. My daughter and I fell in love with the sauna. If you decide to go for it, buy the pass online as soon as you are able. I forget if it was available 60 or 90 days ahead. Suite guests are able to purchase the passes even earlier. I think there also may be a limited number of passes available onboard, and I heard that sometimes they sell day passes onboard, but I'm not sure if they did that for our sailing. Never saw it listed in the dailies.
We were midship a few floors higher than you, so I can't really comment on the cabin, except to say that ours was smaller than prior cabins we've had. Do you have a balcony? If you do, look on the deck plan and check where your beds are. There are two configurations, one with the beds closer to the balcony door and one with the beds closer to the closets. You want a cabin with the beds closer to the closets. It makes it difficult to get into the closets, but gives you much easier access to your balcony.
Oh- thought of one other tip. The elevators after the shows are extremely crowded. There were a couple of times when we wanted to go up multiple floors after the shows. We actually found it much easier to catch an up elevator if we walked down a flight or two, rather than waiting on the same floor as everyone else.
Enjoy your cruise.
Eta: just read the post above me which was posted while I was writing. We didn't go to Cirque, but we met a contortionist from Ethiopa and a juggler from Chile several nights in the sauna. They have more privileges to go places on the ship than other crew, and it was interesting to talk to them.
