Try burrs counrty park. It is in bury which is about 15 miles away. You could get a cab into Bury, then get the metro into Manchester town centre. That will be were your guys will be partying. From town centre the blues ground is ony 10-15 mins walk.
PS Have you got any spare tickets, two guys who work with me are Rangers fans but were unlucky when the applied for tickets.
