we will be going to seaworld for a day during our christmas trip. the day will be sometime between 12/21 and 12/28, but i'm not sure which date. if i take advantage of the 30 day advanced discount of 20% do i have to specify which day i will be there or will it just have to be 30 days or more from the date i print the ticket? also, does the 30 days advanced purchase with the 20% discount include a second day free or is that just good for the 10% on line purchase offer???? THANKS!
