Absolutely right about driving your own cars...I've heard of guys (new-hires, and not-so-new-hires) driving cars from as far away as Dallas, Chicago, Detroit, and many states in the Northeastern US.

It is nice to have your own transportation to take a small break from the Marriott campus to get a nice lunch and dinner from time to time, without being restricted to only the ones near the hotel.

Good luck.
