Not sure if this is hijacking a thread, but...we've stayed at the French Quarters the past two marathon weekends for location purposes. My experiences:
2006 for the half, DH drops me off @ 5:15-5:30, yes, I like to cut it close.

Oh, and yes, he drove me two blocks!

Had a nice leisurely walk of about a mile with three other people. Found port-a-potties, without lines, along the way. Arrived at the start with time to spare. Perfect!

Well, arrived back home and heard about people being turned away. Not able to walk to the start for the half. People were not turned away for the full.
2007, same scenario. We were turned away!!!! Policemen with cars were not letting anyone walk. So, we had to follow a long line of slow moving cars to Epcot parking lot. From there had a long walk to the corrals. Not a good way to start a run!!!
Marathon morning, once again, we were able to hop, skip and jump (the barriers) without a problem. So, my long winded suggestion, ride the bus for the half!!!!!
POFQ is a nice quiet resort. We really enjoyed our stay.
