I had the same experience booking the Fantasmic dining. I saw that the park closes at 8, but when I called last week, before the hours were out, all I could get was 3:30. I almost had 4:00 but I also have a GG of 12. I'm hoping to get something a little later. I don't know when to call back though. I think I read somewhere... something like 30 days before they add later times? I'm afraid to wait too long since we have a large group and need 2 tables. I guess I'll keep checking back before then.
