Hello Lisa,
I'm sure your lovely family are going to enjoy a wonderful
splashtastic time at
Disney's Blizzard Beach Water Park!
I've done a little research on your behalf and think
Tikes's Peak should be great for your dear 6 year old as it allows Guests to remain in their wheelchairs.
These Attractions should provide some watery fun for all the family as they allow Guests to transfer to an available wheelchair:
Chairlift,
Melt-Away Bay and
Ski Patrol Training Camp.
A day spent at any Water Park can be a crowded, noisy affair but to help minimize this you could consider renting a premium cabana space called a
Polar Patio for the day; to discuss your families needs and to make a reservation speak with a Cast Member on 407 939 7529. I can't recommend this option highly enough as it really does provide your family with their own private escape from the heat of the day.
You may also find out some great information by checking
Services for Guests with Mobility Disabilities and
Guests with Disabilities - Frequently Asked Questions.
If I can help you further plan your Walt Disney World Resort vacation please come back and ask me another question.
Have a great Disney day.
- Jane
