20. Do bring your own water bottle and snacks to the parks.
It’s one of the many perks Disney World allows, and one that your wallet will definitely thank you for. There are various water fountains across the park so drink, stop, refill and repeat and you’ll be quenched all day without breaking the bank. Likewise, it’s vital to bring your own snacks because they’ll add up to a hefty price tag especially if you’re traveling in a large group. Save your money for the snacks you can’t get elsewhere like a Dolewhip in Adventureland!
