We were very happy with this entire cruise experience. The Brilliance of the Seas is smaller than other ships that we have traveled on. I thought the food was better on this ship than on the Mariner of the Seas, which we traveled on at Christmastime. However, I liked the larger Centrum on Mariner and the larger Solarium, especially the hottub. So be prepared for some things to just be on a smaller scale.
The Solarium area on Brilliance seemed a lot more hectic, with the Park Cafe in one corner. It got really busy and noisy here on occasion, and I don't think they were really fussy about enforcing the adults only policy.
There are lots of beautiful common areas, though, to listen to music, read, or just watch the ocean go by. The Schooner Bar was one of my favorites. The elevators that look out over the water are also great. And speaking of bars, the view from Starquest is also wonderful, and John from Columbia was a super attentive waiter and an oragami wizard.
3552-A little forward of midship. Very quiet, not a lot of motion, good size window. Equal distance from forward and midship elevator banks, so a bit of a walk either way, in case that is a consideration for other cruisers.
