Jeff, congratulations to you and your wife on your 35th annivesary! Quite a mileston.
Thanks for your review of Allure, which I really enjoyed. The ship is really something. I was also completely overwhelmed by Blue Planet in particular. Also enjoyed the jazz quartet in Jazz on 4, although I don't remember its name. The lead/pianist was a woman.
I thought the food in the dining room was ok, but, as in most restaurants, I found it way too salty.
Did you try to FloRider or zipline? I agree the ship didn't feel crowded, and walking through Central Park was always a quiet, serene experience despite a full ship.
So what are you planning for #40? :)
