DAH is great, but goes by faster than you think so definitely arrive at mix-in or earlier to maximize your time (I wanna say 7 PM but you can check the event page/confirmation email).
My favorite DAH activity is riding Peoplemover alone, 3x in a row - YMMV lol.
I don't think Tiana's is available for some reason, so if you want to do that ride before park close.
