We are staying at the Candy Cane Inn in late February 2003 on a package and the CM who booked us told me a little about the unlimited Fast Passes. Basically each person in your booking will get a Unlimited Fast Pass ticket that you can use to go directly to any Fast Pass Return Line, at any time, and walk directly in. With these special tickets you no longer have to go to a Fast Pass machine to get a Fast Pass, or concern yourself with return time or anything like that. You show the CMs at the Fast Pass Return line your Unlimited Fast Pass and walk right in. They don't take it from you -- you keep it at all times and use it as a Fast Pass entry for any Fast Pass ride any time you want to.
It is an interesting perk idea, though the obvious downside is that if enough people were to use their Unlimited Fast Passes all at the same time for any given ride, suddenly there might be a longer line for the Fast Pass Return, as if it was the Stand By Line.
I don't know if you can use the ticket to get a regular Fast Pass window ticket, though if you can go on any Fast Pass ride at any time, I don't see why you would want or need to.
It's a promotional perk they are testing to get more folks to go through Disney Travel Company and buy packages -- it starts in January 2003, so I guess then we'll start seeing threads about how it is working.
Have a great trip! We are looking forward to staying at the Candy Cane Inn -- we've heard lots of positive reports about it.
