Yep - having lived there for 11 years i can confirm its not easy. If your driving, it may be worth getting there early and parking 15-20 mins from ground and walking. Hotwells area. There is a bus which takes you there - on BCFC site, (although i hope its more reliable than the Shrews bus which just failed to turn up - so we missed 1st 15 mins of the game)
Otherwise theres a pub called the cottage @ 15 mins from ground which has good beers, and i think theres parking and there will be at least 2 Crewe fans in there!!!
Hope that helps a bit...
