Keep in mind that the luau can be cancelled due to incliment weather. We always go to WDW in June and it rains nearly every day. I've been afraid to book the luau because we would then be without an ADR if it was cancelled.
We've been to the Hoop Dee Doo Review twice and loved it both times! There's lots of singing, dancing and corny jokes. The food was very good...fried chicken, beans, cornbread, bbq ribs, salad and strawberry shortcake.
If you have time before or after the HDDR, you can walk around Fort Wilderness. There is a store, a petting zoo, stables and pretty scenery.
