No it isn't!The PSL is yours for life! That's what you're paying for! You get a certificate and everything!
I don't see how having a PSL would make any difference in this instance - either way you'd just have to decide whether on not you want to pay the increased price, or move elsewhere.I suppose the only risk, and one I hadn't considered until I read this thread, is that at some point in the future the club re-classify the lower rows in the WSU into some sort of premium category. And, if they did, would a PSL necessarily protect against losing a seat when that happens?
