Hiya Katy!
Welcome to planDisney! I'm sure you are very excited to be leaving the cold for some time in the sun in just a few weeks! Spending the day at Walt Disney World Water Park sounds like a perfect way to get some Vitamin D and splash the stress away!
Now, I am not sure why your
My Disney Experience Mobile App is showing that both
Disney's Blizzard Beach Water Park and
Disney's Typhoon Lagoon Water Park are closed as that is false. I looked on the US Calendar which has lately been the most accurate. It shows details until February 24, 2024, and every day Disney's Blizzard Beach is set to open from 10:00 AM to 5:00 PM. Disney's Typhoon Lagoon is currently undergoing refurbishment but I highly expect it will open up in time for the hot summer season as that has been the case in the past. If the Parks have to close it would have to be due to some unforeseen circumstance and you will be notified on-site when that happens. Once you arrive in the United States, your calendar should match the more accurate local calendar.
Since it seems you are arriving during the
EPCOT International Festival of the Arts, it is my top tip to visit and enjoy it! It's an amazing festival that runs for a very short amount of time. Since you are visiting during this short window make sure to visit and use this
foodie guide to help pick out what you want to eat!
I hope this helps and assuages any fears or concerns you may have had!
Happy Planning!
