Hi Laura!
Welcome to the Disney Parks Moms Panel. The
transportation throughout Walt Disney World Resort is so incredibly convenient and having to travel without a car seat is always a win for this momma!
If you haven't already I would certainly recommend downloading the
My Disney Experience Mobile App. Based on the time of year and your current location, the app is your best resource for directions between any two given locations within Walt Disney World Resort! You can simply search for the location of anywhere you'd like to go, click on the name for more information and then select
Get Directions. Here you can enter your point of origin and get turn by turn directions including the form of Disney Transportation you'll want to take.
If I check this currently, from Magic Kingdom to
Disney's Blizzard Beach or
Disney's Typhoon Lagoon, you'll want to either walk or take the
Resort Monorail from Magic Kingdom to
Disney's Contemporary Resort. From here you'll board a bus that will take you directly to the water park!
Please come back if we can help in any other way!
