We've done two Disney cruises with our boys now. First time, they were 5 and 6. Last time, 7 and 8. I also had reservations the first time around. It's hard to trust that your kids will be safe in an unfamiliar environment, when you have no experience with it. These are the reasons I had no qualms about leaving them there, after day one:
-The place is locked down like Fort Knox. For an adult to pick up your kids, their room-key and photo must match the ones on file. Also, they must know the secret password. I think it would be next to impossible for anyone to snatch a kid from the clubs (plus, where would they go, anyway?)
-There are counsellors EVERYWHERE. I remember our first cruise, I arrived at the club to find my youngest crying and a counselor kneeling down talking seriously to my older son. I said, "Youngest Son, what's going on?" Counselor said "I think it was something to do with the game they were playing, I'm trying to get this boy's side of the story." "I said, Oldest Son, what happened here?" And the counselor said, "Oh! They're brothers! Well that explains it, then. Sorry, I'll leave this to you!"
-At age 8, they can check themselves out IF you decide you want that option. We did not want that option, so we didn't grant permission for it. So, we knew he was in the club and safe until we went and got him.
-They can send you a text via wave phone if they are sick, or upset, or just bored. When we cruised
RCCL last year, they had nothing like that. I was never worried that my kids weren't OK, but I did worry they were sick of being there with no way to contact us, so I made a lot of unnecessary trips to the club to check in. With
DCL, they want to leave, you get a text, you go get them. Also, if you're going to Palo or Remy you can tell the counsellors that at check-in and they'll make a note of it. That way, if your child comes up after an hour and says they want to text mom and dad, they can check the computer and say, "Hey, your parents are still having a nice dinner and probably can't come get you right now" and them try to engage them in something else.
