Score Free Water at Starbucks
You can get free water at Disney parks in a few places instead of relying on purchasing bottled water, including Starbucks. The coffee shop has tubs of iced water coolers and cups where you can get water for free — without even being a paying customer.
You can also fill up your own reusable water bottle at water fountains near restrooms, and don't be afraid to request a cup of ice water at quick-service restaurants. Pro tip: kids' meals usually come with a free small bottle of water.
