My daughter wants to dress up but more like Disney bounding. I know they dont allow costumes but is something like Disney Bounding ok? I think she is looking at Mario and Luigi but just the overalls and the colored tshirts
That sounds very cute and I can't imagine it being an issue. No one's going to think she's a performer.
This wasn't on a Halloween night, but a few weeks ago, I dressed as Daphne at Universal and didn't have any issues at all. (Pics below for reference.) I don't know if they're more strict for HHN or not, but I can't imagine anyone protesting to what you've described.
