but with even just refilling at the resort it is a great deal, fill up in the morning before you head to the parks, I mean it won't last all day but it's a great start for the morning.....also in the parks if you are a water drinker, and running around DW you need to be a water drinker, you can go to any snack place that have fountain drinks and get free ice water just ask them for i cup of ice water and you get it free, it's a great way to cool down and refresh yourself without being out of pocket for it...something to keep in mind.. have an awesome trip...
