If you don't fancy walking, come out of the Marina Metro stop (Sea Side) and catch the F37 bus (leaves 00-15-30-45) and it'll deposit you right outside Marina Mall - takes about 4 minutes in the bus.
Thanks I was thinking about tomorrow afternoon and thought I didn't want to have to deal with parking. have you been to the street festival is it any good?
The Market is on the Marina walk, which I would say its about a 15 minute walk from the Metro station. If you're going there tonight the metro will probably be quicker, even with the 15 minute walk as traffic will be terrible, and parking will be even worse.
