The answer appears to be that it somewhat stopped already. First game tonight after the price adjustment and we sold about 1000 fewer bleachers than capacity. This could be because I upped the price a dollar, but we essentially broke even with the seats we sold getting the extra buck.
All the other seats sold as before, and I left all those prices the same. I wonder whether they would have come with an increase to those seats ... Ah well. Now we have to do decently on the road and keep them coming.
