Hi, Jennifer!
Welcome back! I am happy to be answering your question again. Did you decide to upgrade to club-level at Disney's Beach Club? If not, I have no doubt you'll be happy at this relaxing resort regardless of your room choice.
You are correct, all guests will need to have their MagicBand present for entry into
Stormalong Bay. This pool area, reserved exclusively for the guests of Disney's Yacht & Beach Club Resort, is the best on property. There is truly something for everyone in the family at this splash-tastic location.
MagicBands are completely waterproof! So no need to take them off while you play. In fact, I recommend keeping them on. This way, there's no need to worry about not having them when restroom breaks are needed (restrooms are near the pool, but outside the gated area), or you decide to head to Hurricane Hanna's for a snack. This Quick Service dining location is located pool-side and accepts MagicBands as a method of payment.
I hope this information helps, Jennifer! Whether you're sliding down the Flying Jib Waterside, or you get caught singing in the rain in a theme park, your MagicBand is ready.
Faith
