Hi Denise ~
Spending a day at Blizzard Beach or Typhoon Lagoon in August sounds like a fabulous idea! We love splurging and reserving a Polar Patio at Blizzard Beach or a Beachcomber Shack at Typhoon Lagoon. It is great to feel pampered for a day.
In the past, they have sometimes offered Extra Magic Hours (EMHs) for Blizzard Beach and Typhoon Lagoon during peak seasons in the warmer months. However, they have not posted the schedule for this summer so we don't know if they will offer them or not at this time.
I would recommend keeping an eye on the online calendar for
Park Hours. From there, select a date on the small calendar icon at the top right of the page. It will bring up the hours for the theme parks, water parks, Downtown Disney and ESPN Wide World of Sports Complex including EMHs. Keep in mind that the online calendars will likely be updated for EMHs closer to August so keep checking back.
Please feel free to visit us with all of your planning questions. It is our pleasure to assist you!
Wishing you minnie magical memories :-) Allison V.
