I'm not going to write a novel here, just a few of my thoughts on the Allure, and some responses to some of the unfavorable reviews I've read:
I was a little concerned about going on the Allure after reading some complaints (about the food, the crowds, the lines, the service, etc.) We found NONE of those issues to be true. It is incredible how they can manage so many people so efficiently. Other than day 1 (when everyone was milling around waiting for their cabins to be ready) and day 7 (when everyone was out doing all their last minute shopping and exploring) we never experienced any problems with crowds or long lines.
Our cabin (superior balcony overlooking the Boardwalk) was larger than similiar cabins we've been in before. We unpacked and put all our clothes away and still had 2 drawers and half a closet unused! The bathroom is larger than we've experienced before, and also had lots of room for storage.
We ate at the main dining room each night, late seating. It was so good that we never felt any desire to try the specialty restaurants, and the service was excellent for our group of 9.
There are so many venues for eating during the day that we never even got to the Windjammer Cafe, which I have heard gets very crowded.
Even on crowded at-sea days, there were empty chairs available on the pool decks (maybe not right next to the pool, but not too far away.) And there were many areas all around the ship that were perfect for just laying back and enjoying the view, or reading a book.
We never had to wait more than 10 minutes to ride the Zip Line, and most of that time was spent getting the gear on.
Every single crewmember we met, without exception, had a great attitude and seemed eager to please.
We didn't have to listen to the incessant announcements for Bingo, Art Auctions, Jewelry Sales, etc. That's all done via in-cabin interactive TV now. Listen if you want, turn it to another channel if you don't.
The biggest problem created by cruising on the Allure is that anything else will now be a letdown.
