I am toooo cheap to pay even a dollar a bottle for, what--water?
If it is even warm, each person should drink lots of water and a family of four could spend $50 to $60 on just WATER--OUCH!
We packed empty gatorade 20 oz bottles, and filled them with ice from our hotels ice machine. Then our drinks were very cold. Everbody had a fanny pack with abottle holder, plus we had a couple extra in a backpack, plus a few more in a small soft sided cooler that was in the bottom of our stroller (that we brought--too cheap to rent!)
Restaurants gave us enough water to fill, if we needed it. Worked great for us, and ice machines have water filters on them, so we did not encounter any yucky taste.
I did not want to bring lunches in the park, but this was an easy way to keep everybody properly hydrated, plus more $$$$ for mickey stuff!! We just did not bring these bottles home with us.
