I have this problem also. We have a lot near state fair grounds. There are multiple concerts and sporting events. Sometimes our address is listed as an option, sometimes there is a "general lot" option, sometimes a VIP parking only option. Last year I reached out multiple times a week to try to get clarity for the parking pass listing - so people know the distance to the venue. Over the last couple years I've sold 100's of parking passes this hasn't made a difference.
I too have sold a lot of parking passes using "General Lots" but on the last game my sales went way down because of another seller using "General Lots" at a much lower price. I was listing mine for $50 per parking space and someone else with a parking lot that was 2.6 miles away listed theirs for $20 per space. I was selling just fine until they posted their spaces and my sales completely stopped.
As a buyer, if you see "General Lots" for $50 and $20 and by not knowing the location, you'll always pick the least expensive. However, in this case, the least expensive was 2.6 miles away and mine is across the street from the venue. Also, StubHub hides duplicate prices unless you select to see all, so most people would not see my listing, only the "General Lots" with the lowest price which was for the other seller. I have asked them on multiple occasions to allow me to but a location address in the description as I think it's a little deceptive to allow someone to purchase a parking pass for an event without them knowing they just bought one where the parking space is 2.6 miles away.
I'll see how this season goes, but I think they could provide a much better experience for both buyers and sellers if they would allow for a brief location description on the listing for the parking lots.
