Hi Alyse!
Yay! It looks like your vacation is almost here. I bet you are super excited!
While there isn't a true "meal plan" for just beverages, there is the next best thing: Refillable Mugs! Walt Disney World offers a drink mug that can be used in an unlimited fashion at resort locations. You can choose from a variety of sodas, coffee, tea, hot chocolate, and more. The only caveat to note is that the mug is refillable only in resorts, not in the parks. This means you can fill it at any resort location (even if you are not a guest of the resort) but not once you arrive at a theme park. Of course, you can always fill it before you head out for the day.
These refillable mugs are now also offered in two styles: A plastic mug with lid and handle or a new, upgraded stainless steel tumbler. If you are a big coffee drinker (like me!), I would recommend upgrading to the vacuum-sealed tumbler. Not only will your drinks stay hot longer, but I find that coffee often leaves an aftertaste even if I wash the plastic mugs well.
Mugs can be purchased in any resort quick-service restaurant. Also, if you do upgrade to any
Disney Dining Plan, the mug is included in the plan. Mug wash stations are also available near refill locations.
I hope this helps! Have a magical vacation!
