HDDR = Hoop Dee Doo Review at Fort Wilderness. It's a dinner show with all you can eat fried chix, ribs, salad, beans, mashed potatoes, and strawberry shortcake and unlimited soft drinks, draft beer, and sangria. I may have forgotten a few things.
The show is great and the food is decent.
We always go when in WDW!
I'm sorry, I can't answer the second half of your question. However, I think the Spirit of Aloha might also be a credit card hold, tho I'm not sure.
I'm sure someone more knowledgeable will come along soon.
Have a great trip!
