Bournemouth has always been pricey -at least for the 8 or 9 years i have punted there but at least it used to have a reasonable choice of a few good girls. But now, I agree, it is now dire. Yes there is Miss Holy and one or two others but that is literally it.
But I must admit, it seems a bit unnecessary to go to Soho for a "walk up" where I would image the quality and service is questionable and you just go for a P&D, and when you take the train fare into account, its a pricey punt. But i haven't done that in about 15 years or more so very much out of touch with the soho scene.
