Is that home of the legendary 'Pleasurewood Hills' theme park? If so, then yes, it is crap. Been to Yarmouth a few times in my youth, but I managed to return home only partially scarred from my experience.
I already told you great yarmouths not great, I should know I live here. two good pubs though the ship and allens bar both on greyfriers road, at least yarmouth is quiet ish at the moment, in the summer it really is hell
