Just one thing that may be of interest.
If you buy in the US, Annual Passes are $179 and work out cheaper than the 4 park flex ticket, which are $202.
You also get a host of benefits including free parking, $9 a time, and discounts at shops and restaurants etc
Furthermore if you (like us) go each year, to renew it is just $99.
Obviously you do not get Sea World and WetnWild included though.
It is just a thought, a different option perhaps. The Flex tickets are good value for money also.
