Hey John and DesertGuy,
Why don't you come over and register on the Cruise Critic roll call board. We are up to about 18 now I think, and if we get to 20 or25 (not sure which) Celebrity will host a get together for us. Go to the "Celebrity connections" on the boards and look for our sailing.
D (a university prof) and I (RN) raised 5 kids and now have 18 Grands. We too have a very low tolerance for poorly supervised children and are not embarrased to speak to them or their parents if the need arises. However, after 11 cruises, we have only had to do that once. Hmm--maybe our tolerance isn't that low after all.
