My husband and I took the 8 night Christmas voyage on the Quest. I've written a more detailed trip report with photos on the Azamara forum of Cruise Critic but here's the more compressed version.
Dining: excellent. We did not dine at the two specialty restaurants this time but will do so the next as they looked very inviting. We ate mostly at the outdoor Sunset Bar, having gotten our food at the Windows Cafe buffet. Each night had a different theme--Asian, French, Turkish, etc. The staff was always willing to tell you about the food if you didn't know what all the items were. The dinners we had at Discoveries were delicious and service was efficient and unobtrusive. High marks there.
Public Rooms: very traditional decor that was considerably enhanced by contemporary artwork, carpets, and accent items. It all worked beautifully together.
Our cabin was at the aft end of the ship. No vibrations or engine noises. The cabin is on the small side but comfortably appointed and we liked it very much. We slept well in the bed. Adequate storage. The bathroom is very small but it too has enough storage. The shower must be the smallest around but it did the job of getting us clean and in the end, was really a non-issue.
