Can you use the Annual Pass (AP) at the Typhoon Lagoon or Blizzard Beach.
Only if its the super Expensive premier pass valid at wdw and DL California. There is a waterpark annual pass available to buy. I think it costs about $100 and there is a cheaper after 2pm waterpark annual pass for Florida residents.
Here’s a list of the annual passes. The starred ones have water park options.
There’s a Florida Resident Seasonal Pass, Epcot After 4 Pass and a Florida Resident Weekday Select Pass, which does not include water parks.
There’s the standard Annual Pass (available for anyone), which does not include water parks.
****There’s the Premium Annual Pass, which does include water parks (currently $649)
*****There’s a Florida Resident Water Parks after 2 PM Pass (Must be Florida resident, priced at $65 for adults, $59 for kids)
*****There’s also the Premier Park Pass (which is both an east coast and west coast pass) that includes water parks and is $1099 per person.
Aside from the Premier Park Pass, you can get details on all of them here:
