In reply to Frank the Husky:
I'm not sure that I expected someone to "dislike" my post, but there you go. For the benefit of the person who did that and the guy who thinks eight quid is a bit expensive, there are things you probably didn't know. That money gets you in for the whole day, not just 30 minutes. It repays for the investment they made, as well as paying for more obvious things like wages, insurance, tax, utilities, rates, national insurance contributions, maintenance, computer systems, subscriptions to software and probably a few other things too. Perhaps only a pound of your entry fee is profit. Once you know those things, you'll hopefully appreciate that £8 is pretty good value.
