Exactly, would be a great fit. And I agree about Albert potentially become a short mascot for the park in that case.
A ride like Mystic Manor -- a longish, family friendly dark ride -- is exactly what DAK would need once the current round of expansion (RoL, Pandora) comes online. Now, I don't think any of us are foolish enough to suggest that more money would be spent in that park in the near future or that it is even being considered, but I'd like for that to be the case.
I have this dream that they'd do a similar "celebration" for WDW/MK's 50th anniversary that they did for DL -- have the different parks get a "gift" of an attraction from somewhere else worldwide. In that scenario, Mystic Manor would be the perfect addition for DAK.
