Our auto club has combo tickets for Sea World/Busch Gardens- they are for unlimited times to each park and expire 14 days after first use.......it is my understanding these tickets have an expiry date of December 31, 2011.....we are going from Dec 24 to January 7th....if we get to the parks before the 31st are we good to get in for 14 days after even though that would put us past the Dec 31 expiry date on ticket? What if I only got to Busch Gardens before the 31st? Would I still be able to get into Sea World?
