Problem is Mike as you won't be a member you can't book in advance so will have to take your chance as to who is available when you arrive, my advise is to register as a member when you are there and this covers both locations.
Of the girls on the rota tomorrow that i've seen I would recommend Abbie @ Northenden but avoid Nicole & Lilly, I did also see Billie a few years back and remember she gave a pretty good service
