This is the exact time we went this year. We came in on the Marathon weekend and left after the MLK weekend. We were there for 10 nights. The marathon weekend was not as bad as far as crowds in the parks go, but as for getting around it was a nightmare. They have roads blocked off and the traffic was crazy. We were trying to return a rental car to the car care center and we couldnt even cross the road because of the marathon. We could stand on the other side and yet couldnt get across. We ended up dropping off at the Dolphin and had to take a cab back to POP. It took us 2 hours to return it and it was maybe 7 mins from POP. The MLK weekend was another story-CROWDS

everywhere!!!! There were also sporting groups there and I thought it was just crazy. It was hard to get things done and the wait times were really long. I would pick marathon weekend over MLK any day. Weather wise it was pretty good. Only a few nights out of our 10 did we have to break out the sweatjackets.
