Just a note to everyone planning thier first
Disney Cruise with kids in the 11-12 year old range, we took two cruise last year and our twins were 11 on both of them.
As much as it seems like kids are not given a lot of freedom on the ship (based on responses from this board), the thing is EVERY child that my kids made friends with WERE given a freedom to go around the ship as the pleased. My kids were mad that I would ONLY let them go back to our room (again our room was on deck 5 right around the corner from the lab--we pick that location on purpose so that our kids can easily return to the room on their own without having to walk by a lot of other staterooms).
At one point, my DD checked herself out of the lab and brought back this 10 year old girl to our room to ask if they could go swimming. I told her that we could go then (and our rule is that there is no swimming unless we are with them). I asked if they wanted to go back to the lab, the other little girl said NO, so I offered to walk her to her room (she thought I was crazy). My DD and I walked her to her room, but there were NO parents. I asked her what her parents rule was about being in the room alone without them and she said they didn't care. So I told her to lock the door and we left her (they were in a Cat. 3, so they were on deck 8). After about 1/2 hour we went on deck 9 to get pizza and we saw this girl (NO parents) swimming alone in the pool. She could do whatever she wanted to do, her parents didn't care.
Then my DDs made friends with some other kids who could go to the arcade and buy as many cards as they wanted (my kids couldn't charge on their KTTW cards) and be there by themselves whenever they wanted.
So, my point is this. As much as it seems like (bases on responses from this board) that parents DON'T let their kids 10 and older go around the ship on their own, when you get there you will find that just isn't the case. I was the 'mean' mommy because I only let my kids go back to the room by themselves. But based on what you would read on this board, that is too much to allow an 11 year old to go back to the room by themselves.
Also, I will say that until my DDs turned 11, (we had been on 5 cruises at that time) we did NOT let them check themselves out or be in the room alone. Many kids do this before 11, but my didn't.
I'm not saying to do what other do, I am just saying that you should be prepared to be the 'mean mommy or daddy' because most of the other kids in the 11-12 year old range are going to be coming and going as they please. You have to set the limits for your own child, but be prepared to find out that parents are a LOT more relaxed with rules on the ship than it would appear from the posts you read on these boards.
Anyway, have a great trip, and you will figure out what is right for you and your kids while you are on board. I told my kids I would decide while we were on board what the limits would be, and as week progressed our rules relaxed a little (but never to the extent of all of their new friends).
Good Luck!
