It did seem odd, especially as the route didn't accept area tickets - that might have been seen as helping draw tourists to travel to the area by public transport.
I had a bit of a heated argument with the Stagecoach MD about this. His take was that to have accepted Wayfarers and passes would have meant a larger subsidy would have been needed. To me, that just means the service as conceived wasn't viable, at least not with an operator who seemingly wasn't prepared to take any commercial risk themselves.
The Wayfarer issue is one that has raised it's head elsewhere though - at the moment, the revenue sits with whoever sells the ticket. I know Hulleys aren't happy about this as most Wayfarers they have to accept are sold outside their network area for travel in to it. It is similar here, but also highlights another issue with this bus - that, one route aside, the Peak Sightseer is in an area Stagecoach simply don't serve. They might get the odd Wayfarer sale on the 65, but as it's two-hourly it won't be many.
An operator who had services linking to this area, such as Trent/TM or Hulleys, would likely have been more willing to accept Wayfarers on the service as they would gain some sales and therefore revenue.
I'm not sure this year was the time to be launching a service such as this with driver shortages, and I'm not sure Stagecoach were the best ones to run it with their profit before all else mantra and lack of any real history in the area. More in general though, I feel the way Derbyshire County Council are spending their Bus Service Improvement Plan (BSIP) money is very poor and wasteful. Indeed it seems to be causing more issues than it's helping improve services. I certainly think that one condition of accepting BSIP money should have been to not withdraw any commercial services during the same time period.
