Hey, no problem. I don't know what Miami and Sarasota water is like as I've never been to either place. My experience is that the water in the Panhandle is usually pretty good, it's when you start heading down the peninsula that the water starts getting no so good.
At Disney if I'm thirsty I'll grab a glass of ice water from one of the carts scattered around that sell fountain drinks. That water is filtered, free, and colder than any from a fountain.
