5. Carry water bottles and snacks in the parks
Snacks and drinks can add up, and with all the walking in the Florida heat, you work up an appetite quickly around WDW. Even if you're on the dining plan, you only get a certain amount of snack credits per day. Carrying a water bottle with a filter will allow you to fill up at any sink or water filter. Quick service restaurants will give you free ice that you can put in your water bottle. Having snacks you've packed will minimize your chances of blowing your budget on churros. Save your snack credits until the craving for a Mickey ice cream bar hits, or put your meal credits toward a character meal!
