Hey,
It's meant to be one of the best dryslopes in the country.... It is a bit dull to be fair and unless you go on a slalom or freestyle night I can't see you wanting to regularly use it.
They do have equipment for you to rent and usually they're pretty cool about putting the sprinklers on if you want it a little bit quicker.
Price wise it's a few pounds or so for 90 minutes but they rarely kick you off after 90 minutes.
Hope that helped.
