I'm not getting my hopes up, but I am wondering if anyone has had any luck in doing special pricing for aisle seats without simply adding new price zones to the map just to rezone those seats into? We just had a rental a few weeks ago that requested this at show build. They had 9 price zones so we had to have 18 price zones setup for the show; it was a rental so we just had to go along with it. And now another show is requesting this. This new show is a co promotion and will appear as part of our main season, so we get a say, but our leadership team thinks its a good idea. Our season shows usually use a 5 price map, that has 10 zones, 5 for the main floor and 5 for balcony to allow for easy discounts and repricing based on section. This is definitely the kind of show to want to increase prices on the floor, or do balcony only discounts, but I really don't want to have to create 20 price zones for a 5 price show. And it seems like this might be happening more often from now on. But if that is the only solution, then it is what it is.
I unfortunately don't think you have an option besides making the 18 zones. There's no way (that I can think of, at least) to use Pricing Rules to fire on aisle seats since it's not in any of the criteria that you can use. As someone that once had to build a 24 zone map for a rental (not aisle specific, just a promoter that didn't know what they wanted and had never been in a venue our size) I empathize completely.
