Cahill,you will pass through Mottram,you could take M/way from there to Hyde[3 MLS] come off slip taking the left,go through lights,Clarendon car parks just to the right,park in council not private sector ,£1 for 3 hrs long stay cant cost much.
Town center has bus station [guess 400 yd walk.]
This will cut out city routes. Parky's cuts across some major Rds.
There are bus stops closer,but I don't know routes.
