MyFun members (free membership) can buy an Annual Pass to any one of the three passes for $99 until the 31st of August 2008. This offer is only available online, as Annual Membership purchased at ticket windows costs $179.
This is something to consider for those who are likely to visit any of the parks twice or more in the next year, as the annual membership costs less than two individual ticket entries.
After purchasing online, you will be issued with a single entry ticket. Scan this ticket at an entry gate and proceed to Guest Services to have an annual card issued.
