I won't be surprised if you see something like
Disneyland's "13 day" policy - meaning that all days on the ticket must be used within 13 days of first admission - tickets sold outside of packages. I also wouldn't be surprsed if all tickets purchased with resorts become "length of stay" as well. Ticketing is always a big bone on contention within WDW management (too many parties have too many behaviors they want to influence). The end result is always a comprimise of some sort.
I remember using Lenght of Stay passes around 2003 and/or 2004.
The tickets expired at the end of our stay.
Here is the old price list from 2004:
2 and 3 Day Tickets
Not the same as Park Hopper Tickets. Can only be used for one park per day - Magic Kingdom, MGM, Epcot, or Animal Kingdom.
