There is a hotel they recommend, and it has a van to take you to/from the interview site. Sorry, I forget which one it was.
Good luck. The interview process has changed since I interviewed (5/01) but the best advice I can give is try to be as relaxed as you can, and be confident, but not cocky.
It's not a real touchy-feely deal, nor is it a real technical interview, either. It's basically a get-to-know-you, why do you want to work here, will you be happy here, will we be happy with you, will you be able to upgrade quickly if we need you to . .
Good Luck. I started a year ago, and have been very happy here. Hope to see you on-board.
