Hiya Stephanie,
Welcome to planDisney! I hope you and your group have a magical time at Walt Disney World Resort. Large groups are always extra magical because there is always someone to ride an attraction with or wait in line for DOLE Whip with. Plus, having built-in exit buddies ensures everyone is accounted for.
Thank you for your excellent question! Yes, you can bring your own water bottle to the Theme Parks. Even in October, you can get dehydrated in Florida, and with eight Guests, it is definitely not cost-effective to purchase bottled water all day. But with a refillable bottle, you can use the water fountains throughout the Theme Parks and use that money to buy yummy treats and souvenirs! One last thing, if your water bottle has a straw attachment, please make sure the straw isn’t plastic. Plastic straws are
prohibited at Disney’s Animal Kingdom Theme Park, water parks, and Disney’s Animal Kingdom Lodge.
Come back and see us for any last-minute planning tips!
Happy Planning,
Ashley F.
