Tintagel v Stonehenge: too expensive v extortionate?

There have been complaints that the price which English Heritage charges to visit Tintagel Castle is unreasonably high. For instance, a Family Ticket (2 adults, up to 3 children) costs £38.50. It has been pointed out that at that rate it will be no time at all before the cost of the new bridge is recovered. So why so high?

But then compare it with the identical Family Ticket at Stonehenge (2 Adults, up to 3 children), £52. So £13.50 more than Tintagel. Why the discrepancy? We don’t know, but you are free to speculate whether the discrepancy will grow far larger once English Heritage secures a virtual monopoly on most people even seeing Stonehenge.
