Correct, Diggler. Once you have purchased a Final Five ticket package, the X will send you a form every year after to give you a choice to renew. You'll get to keep your same seats if you want them, or you can try and upgrade the location but that is not guarenteed. There is only a $5 charge for handling each year, so that is a HUGE bonus over working with Ticketnazi. Oh, and if you want to purchase additional tickets in future years they give you the option to do that as well, however, I bet your location would move in order to find seats to accomodate your full group.
I don't believe you get this service if you just buy tickets for a game. I think you need to purchase the whole ticket package.
