Edited my original post (which was poorly written) to share some TSL advice: FastPass is wonky! Things are coming and going, availability isn't there one minute and is the next, and my window opened, I swear, early. So my advice: if you've got a trip coming up in 60 days or so, don't just check once and go, "Darn there's nothing there!" Keep refreshing, there's all kinds of magic afoot.
