For room service, we only ordered the sail away cheese platter. It had cheese, some fruit, and glutenous crackers - but they were prepackaged so we didn't mind. I brought gf protein/snack bars just in case. We really only used these in Nassau when we went to Atlantis. As for Castaway Cay, we preordered our meal with our head server. He gave us a time to meet him at Cookies. He brought out so much food for us it was unbelievable! So, there were no troubles there! I don't know anything about the kids club. I have heard more recently that you can get GF pizza on deck which will be awesome! We never asked about this on our last cruise, but we will this time. I believe that the ice cream on deck was all gluten free so that was always a snack option.
