Just back from the Poly last Sunday. They had bottled water, but it was in large glass bottles that could not be brought to the parks (I also saw them give some kids small bottles, but they were also glass). But, we asked (and received every time we requested it) two large bottles to take to our room. We just filled out water bottles brought from home with the bottled water to bring into the parks. Sometimes we just filled the bottles with ice and bottled water in the lounge...so although it wasn't the most convienient thing for us, it worked and saved us $2.50 a bottle for water in the parks.
