In reply to J Dunne: For what its worth John, when I was living close to Manchester and using the MCS, the staff were fine, generally helpful about things like sensible places to leave your car and other little useful points. The wall gets crowded at popular times, but that is just a sign of success - you can hardly expect a business to turn people away, though at all popular walls (like the Westway or Castle in London), there might come a point where the numbers have to be limited at any one time.
Odd for someone to comment on other climbers attitudes - hardly the responsibility of the wall if another climber gives you attitude. In any case, that is like bad/dangerous driving - you never notice the good and reasonable majority, while the *rsehole sticks out like a sore thumb.
The prices seem pretty comparable with other walls of a similar size - it is always amazing what people expect from a wall. At a climbing wall you can stay as long as you want, while at a squash/tennis court you get what? 45 - 60 mins for an hour, usually £5 - £8 per person. If you think of the costs of running a wall (light, staff, the wall itself, the dreaded liability insurance, etc, etc), nobody is going retire to a sunny beach on the proceeds of running a climbing wall. Most climbers above all want regular updating of well set routes, how much do you think that costs? The days of "build a wall with a few bricks sticking out and leave it for 20 years" are long gone. Ultimately you get what you pay for.
