Snakes tend to acclimatize to people, and that seems to be happening with greater frequency in WDW. Ick.
The weather was pretty dramatic when you were here! We missed much of it (just north of where you were) but saw on the news reports that you were having some torrential stuff.
It's nice that you had a good time overall though. I love otters! We once stood and watched them for quite some time at DTD. They were playing in the little stream that runs through there.
