Universal has two massive parking garages for two theme parks and City walk,I must have left those garages hundreds of times with huge crowds all leaving at the same time and I cant recall ever having a real delay getting out.Seriously, those garages must have like 12-16 exits between them,it seems like every time you exit them you go a different way,whoever designed them was a genius.I agree with the poster who says DHS should get one,that park needs as much space as possible and a parking garage done correctly would still work with its theme.
We must have rotten luck then - the two times we've parked at universal we've gotten stuck in a lot of traffic exiting at the end of the day. They may have a lot of exits, but many of them feed into one area.
