We're gulping this advice up.

What's clear and hand-held and expensive all over? Bottled water at Disney World.

That's why smart Disney World travelers come prepared and tote along their own reusable water bottles, which you can refill at water fountains around the park. It's a shame we didn't think of this savvy idea, oh, five vacations ago. "Reusable water bottles are always on the list of things that my family brings with us to the Walt Disney World Resort theme parks.," writes Crystal B. on the Disney Parks moms panel. "Guests are welcome to bring bottles, cups and mugs into the theme parks provided that they are not glass containers and they do not bring alcohol into the theme parks. You can check out the Walt Disney World Resort Park Rules for the complete list of prohibited items. I like to bring insulated, stainless steel bottles with us since they keep our water cold for so long."

Crystal adds that you can also get a free cup of ice water at quick service restaurants throughout the park when you place your order. Either use this cold water to fill up your reusable bottle, or gulp down with your meal.

In addition to being wallet-friendly, this simple move is eco-friendly, as using your own reusable water bottle helps to cut down on the overall amount of single-use plastic waste created.

Curious if you can bring your own outside food into Disney World? We've got that answer covered for you, too. More money for souvenirs, friends and Mouseketeers.
