Interested to see your review. One of my (many) complaints about RCCL on the Serenade was that they only had 1 "included" food outlet during the day other than the Windjammer (which was closed from 2pm-5pm) called the Park Cafe that (1) had an extremely limited menu, and (2) was in the adult section, so we were always unsure if our DD could go in there to get something. On that ship, Pizza, Burgers, and the Ice Cream machines are in the Windjammer, so you couldn't get them all day. Also, it was tough to find something when you'd get back on the ship early as it didn't open back up until 5pm...
Now, that could have been a symptom of our cruise (which, had about 1/3 of the crew walk off in a contract dispute prior to our sailing), but I really hated the limited selection of food during the day...
