It's great to see you here today at the Disney Parks Moms Panel, Claire!
As far as I can remember, I have not seen
MagicBands for sale at
Disney's Typhoon Lagoon Water Park. I also checked the Shop Merchandise feature on the
My Disney Experience app and did not see any of the MagicBands listed there for sale at any of the Water Parks. That does not mean that you won't be able to find them there, though! Merchandise locations switch up their inventory all the time so it's definitely worth stopping by
Singapore Sal's when you get there to see if they have any MagicBands in stock.
You still have a few options if you want to pick up your MagicBands before you ever enter a Theme Park. There is a very large selection at
World of Disney in
Disney Springs, so you can swing by there to pick one up at the beginning of your trip! MagicBands are also available at some of the merchandise locations that are right outside of the gates of the Theme Parks, like
The Outpost Shop at
Disney's Animal Kingdom or Mickey's Gift Station at the Transportation and Ticket Center, which is where you park your car to catch the
monorail or
ferry boat to get to
Magic Kingdom Park for the day.
I hope this answers your question, Claire, and please let us know if there's anything else we can do to help you plan your magical vacation!
