I just tried to use a ticket on Thursday that was a Magic Your Way ticket from Feb. 2006, with 4 days left, non-expiring, park hopper. The lady at the gate seemed to know what to do and took it away. I waited 20 minutes for her to return, at which point she informed me that while they usually take WDW tickets, that particular one would not work there for some reason and she had talked to someone at WDW to try to help, but they could not make it work, even though it did indeed have days left. So... moral of the story... definitely give it a try. It may work. It will probably work... but have a back-up plan in place, as there are no guarantees.
