That day sounds rough! I too have done the Cheat. Never gone during Cheat Fest, but always wanted too. Some friends are going this weekend, but I have the kids and that is more important to me.
We hiked out from the takeout of the Upper or Lower Meadow (I can't remember which), but that was miserable it is fairly vertical switchback and a long way to the car!
