YUP! The 100 story happened to us. We let the kids go on ahead
of us to the arcade. When we got they they excitedly told us "LOOK, you just put your key to the room in that machine and you get all the arcade cards you want"!!!!!To our horror, we found 10, $10 acrcade cards! Luckly we took them down to GS at once and they took them off our bill. I'm sure if they had used them it would have been a different story.
Moral of the story, if you do not what your kids to charge to the room, go to GS after boarding and remove charging prevs.I THOUGHT I had done this already at check in at the Port.
