We are a family of 6 and have been WDW before, but never during the summer. I want to make sure we stay hydrated, but don't want to lug around too many bottles of water. We will take a mid-afternoon break from the parks so we can re-hydrate once back at the resort. But should I just take one bottle per person and then re-fill at water fountains and add crystal light packets?? We will have a stroller, but carrying alot from the bus stop to the park can still be alot. ANy suggestions would be greatly appreciated!
