Buses - I've told this story before and most people don't have similar tales, but in 2013, I was at the bus stop at like 3:15 at Port Orleans Riverside. Somewhere between three to five full buses passed us by on the way to the marathon. It was after 4 am when some poor driver took pity on us and let us stand in the aisle of his bus so we made it on time.
Now - I don't know if this is because we (as in other runners, and a large amount) were standing at one of the resort bus stops instead of the main stop at the front of the resort or what (but no one else seemed to have this issue at other non-main stops) or what, but I don't want to go through that again.
