I'm sure it won't be a problem.
My 11 year old was on
Castaway Cay in the Ocean Quest club (doing activities with them). I told her to meet me in our meeting spot after it was over. At 3 p.m., when the activities were over, she never showed up. We waited and waited. I had her room key, so I knew she wasn't on the ship.
Wrong.
I got a beep at 3:30 (they gave me a beeper for my 4 year old) and the beeper said "FYI she (dd 11) is back in the stateroom on the ship" !!
HUH? How was that possible? I had her room key.
Turns out, according to dd, after kids' club, she told the camp counselor that she was to meet me (remember they all have sign in and sign out privileges) and the counselor said it was easier to just go back on the ship. Counselor told the security people to let her on, they did. Then counselor got guest services to open our stateroom door for her.
I found that very strange. I'm still confused by it.
