I've been listening to a podcast where they keep saying that WDW built many of the queues indoors to protect the guests from rain, but I kept thinking the whole time that they need to be indoor because of the heat more than the rain!
It was this during the weekend of the 4th for our visit. It only rained on the 3rd, which was welcome. The 4th & 5th were dreadful, no cool down @ night, just less UV.
Not any better in SW FL, it's all end of August weather right now, craziness.
