^^^ I think they'll probably have her in mermaid form.... though I'd hope they'd be smart enough to take her out of Ariel's Grotto (the restaurant)....
I imagine they'll probably set up her M&G by the attraction similar to WDW's where it's more enclosed (so there's no more shell turning in front of guests).... hopefully they'll scrap that ugly rock that we use though- DL's shell is much nicer looking. You know what would be cool?? (But they'll never spend this kind of money simply for a M&G) If they set it up like some places do shark tanks- you've got tank above, below, and around you, just separated by some heavy-duty glass!
