This comes from our recent trip to Disneyland Paris with our 2 kids (8 and 6).
It was the first time for all of us. DH and I were really surprised to notice the amount of childless adult visitors and the rides they chose to go on-Dumbo, Slinky Dog, Pinocchio etc. These people ranged from young couples to 40/50 year olds. The problem is that the seats are quite small and clearly meant for kids but these people were queuing (and in some cases pushing past kids) therefore kids were waiting 45 mins to get on.
I cannot understand it as I wouldn't go without the kids, particularly on rides such as Dumbo. However, I get that everyone has their own interests.
AIBU to suggest Disney should have separate days for adult only and then families? I know they won't but it was really annoying while we there!
