You spend all day in the hot sun. Sweaty, smelling a little ripe. You get regular breaks by ducking into a nice Air Conditioned Ride. But all you really want is a nice cold drink without having to pay for a soft drink, or frozen lemonade. You've got your empty water bottle from the hotel, you go to a water fountain to fill it up. Put the bottle to your lips, take a long sip....and all you taste is rotten eggs and sulfur from the Florida ground water. Blech. I can never get used to the water, and it is honestly the only thing I look forward to when leaving. The restaurants seem to have filtered water for tap water at the tables, but the park water fountains do not. I wonder if a solution would be too costly...or if Disney is hoping families will spend few extra bucks in the park buying bottled water or sodas.
