We ate at Kona the last week in April. It was one of the few places that had a space available for 7 people that night. We had to have a sort of late PS, but we were able to make one, at guest services. I'd say, figure out what night you want to go, and then go down to guest services at your hotel and make the PS there, if you don't know before you leave for Disney. We had an awesome dinner, but I will say that at 7 at night, there wasn't a table available.
