We probably aren't giving up our plan because we like being able to get into the Norfolk Southern area. I've got a large group and very few have 6+ games, so there's less of an inconvenience factor. I enjoy just going, and by Metro I'm typically home in an hour, which is fine.
I agree on the resale aspect but we live with it. Frankly, I eat a lot of seats. If I take a couple and don't fill the 4th seat, it's like I am paying double. I'd be tempted to pick up some of the other deals, like $65 a month to go to as many games as I want, were it just me.
