We dealt with this tonight. After 2 hours of virtually constant torrential rain (. Ie. there was a bit of flooded areas) we gave up and came back to the hotel. (It was also bedtime). When things looked threatening, we hopped into the carrousel of progress then rode the people over 4 times. At a break, we went to haunted mansion. Basically- ponchos, Tevas, and a good stroller cover (perhaps 2). Radar app on phone is also helpful. A good attitude also helps. Oh and last week they said sunny all day, high of 80. It has been 94 and stormed last night, tonight, and supposed to now tomorrow and Friday. Plan for anything.
