I went to the last one. It was great..
Some pointers:
They made us promise not to consume alcohol for the week..
There are bars around town. One called "The Palm" is pretty nice. Couldn't tell ya how I know about that though
Bring a fan, the W&L dorms are not air conditioned (or they don't turn it on for us).
If you can get them to put you up at the Educational Foundation, do it! Some guys got to stay up there or at local hotels.
If you're flying, make sure you have a way to be driven around town -- should be plenty of people with room in their cars.
It's a hell of a time. Enjoy yourself and actually go to the classes they offer (even the optional ones) they were helpful.
