In January of 1999 my family & I were checking out of the Wilderness Lodge the day of the Marathon & only realized it a few days into our WDW trip that we would departe on that day. We asked a CM at the Wilderness Lodge how it would be trying to get to the Airport, since we had a 10:00 AM flight. He said you will have no problems at all, which he thought since that is what he told us. When we drove away the day we checked out, it was bad. All cars were in a single line going very slow & we had thought we were going to miss our flight because of this. We asked some security CM's about getting to the Airport, because we said we might miss our flight. They did not seem to care as they said just keep following everyone else. Thankfully we eventually went the way the MK Resort buses go to DTD, passing by Fort Wilderness & we were able to drop off our rental car, check in for our flight with plenty of time to spare. However because of that day we have refused to ever check out of WDW the day of the Marathon, if we happen to have a vacation that goes into the day it is supost to happen.
