I suggest the companion bathrooms. I believe there are six in the park. There you'd have complete privacy and more convenience.
I won't use them to change The only time I do take advantage of them is when I need to deal with my personal medical issue, which is awkward to do in a regular, small bathroom stall.I really wouldn’t suggest that. When a companion room is needed, it’s needed, and it’s not kind to those who *have to* use the companion rooms to use them in order to change clothing for what truly amounts to vanity reasons.
Confession: I bought too many outfits for my upcoming trip, and I want to wear them all. Disneybounding problems for sure.
I assume there's not a dressing room anywhere to change mid-day, correct?
