Good Luck! I hope you can get one. We went to Ohana a week ago and was in check in behind a family who didn't have reservations and was trying to get a table. Needless to say they didn't. The cast member even was nice enough to check for the rest of the days they were on vacation and there was nothing available. Moral of the story, try your best to get an ADR. Now, it is more likely for you to get a ADR on the day of then it is for you to get a table without a ADR. When we were there in July, we we didn't have a ADR for anywhere but decided we would see what was available for later that day. Sure enough Ohana came up and we got it as soon as we saw it. So keep checking.
