I highly doubt that anything is even available at this point, especially this week between Christmas and New Years. I maybe wrong, but I think alot of the packages sell out rather quickly after they are announced in August or Sept.
I was able to get a 2:00 sitting at the Coral Reef. We have to go to the 5:00 show but I think that will be ok. We went to a late showing last year. Never been to the Coral Reef but I have read good reviews.
