My fiance and I took a cruise on the Allure this July after having a "taste" of the Oasis class after our December 2010 5-night trip. The Oasis was a very special cruise for us (we got engaged) so we were definitely looking forward to the features of the Oasis plus some new stuff on the Allure.
Positives:
-The specialty restaurants are all fantastic. We ate at the Samba Room, Chops, Giovanni's Table, 150 Central Park, Rita's, and Johnny Rockets and they were all amazing. Definitely extra points go to 150 Central Park with the most delicious tasting menu we've ever had (every plate they brought out was better than the last) and these fantastic melon martinis... omg, still think about them.
A little far from the elevator... not the best view of central park
