People buy 12 hamburger buns, use 6 now and freeze 6 for later use. OK maybe not buns but certainly meat. Years ago virtually all Disney tickets never expired. There was a discount, but not a huge discount, as you added days. MYW tikcets allowed guests to add extra days for literally a few dollars. The intent was those days would be used during your current trip. The extra cost to add non-expiry went up at least once. Basically to remove the significant discount you received in adding extra days to a base ticket. Disney could just increase the cost for no-expiry. Make it even less attractive. Add me to the posters who think the RFID wrist bands may be the reason why Disney might wind up getting rid of no-expiry altogether.
