Hiya Helen!
Welcome to planDisney, and thanks for visiting with your question. What an excellent plan to experience the Disney Water Parks during your upcoming stay. September is a great time of year to do so!
First, I love that you've shared your passion for Blizzard Beach with me. Can I say something crazy? My family has only been to
Typhoon Lagoon, and we loved it. So it sounds like we need to add
Blizzard Beach to our Disney bucket list! If you tell me Blizzard Beach also has those amazing mini donuts at the Joffrey's Coffee cart... well then, that will really seal the deal for me.
Let's start with what we know about the operating plans for both of these magical water parks in upcoming weeks. The
Disney Parks Blog announced that for the first time in forever, BOTH parks will be open at the same time from May 21- September 7. There's been lots of excitement over this year's
free water park admission on arrival day perk, and both parks have been bustling with guests and splashtastic fun lately! That being said, we don't know yet what the exact plan with be for your mid-September vacation dates. My recommendation is to watch the
Park Operating Calendar, which typically posts schedules and park hours around 60 days in advance. This may be your earliest and best clue as to which park(s) will be open when you arrive.
I hope this helps, Helen. I'll be sending pixie-dust your way to have a wonderful visit to Walt Disney World! Please don't hesitate to
send me any other questions you may have.
The magic is calling!
Tami
