If you can't get to a park to grab a bus, I recommend a cab. We went to DTD to catch a bus and there were so many people in line, that another group formed a second line. Both tried to get on the bus at the same time, it got ugly. I ended up having to wait for the third bus to come around before getting on one (and sprained my ankle, but that was due to one very rude woman who did not want to wait in line.) Too many people try to leave DTD as the shops are closing.
