I actually prefer cold rain to warm rain. It's weird because I of course like warm showers, but warm rain? Nope.
I haven't been to WDW yet, but I'm familiar with east coast weather, and it's not fun. I first experienced humidity in New Jersey; worst summer ever, in terms of the weather. And the worst part about was it never cooled off at night. My family and I were miserable. Same for New York, it was hot and sticky the whole time we were there. Humidity and I have never been friends, and never will be. I prefer dry heat.
I like that it cools down at night over here out west. Growing up in Los Angeles, I've become very spoiled when it comes to weather. Yesterday and today was the first time we had seen rain, lightning, and thunder in months (I actually think that was the first time I had seen lightning and heard thunder this year). The beauty of living in California is choice in microclimate. It'll be sunny again this week (yay), but if I wanted snow, I wouldn't have to drive two hours and I'd find it. Same for desert, I could find that as well in less than two hours. One could literally go surfing, hiking, and skiing here in one day.
The land of spoiled children. Haha.
