Yep, she wasn't floating back in my last trip to DL (Late June). I kind of prefer it that way. Don't get me wrong, I like DL's HM WAY better, but since WDW uses a rear projection, the floating effect looks much more convincing. I say until DL gets a rear projector Leota should stay on her stand. It just looks better.
When I was at WDW in December, she wasn't floating there, either. I assumed it was just malfunctioning that day, but maybe not.
Anyway, I prefer her staying on the table to floating. She anchors the scene better that way; with the floating there's just too much motion going on.
