I think the closest similar off would be the two day ticket straight from Disney. The 2 Day Hoppers are not longer being put out by Disney, and the ones that they put out last are only valid until Dec. 31/05. They didn't make any more after that... that's when they started the Magic Your Way plan, so I imagine that Mousesavers is trying to get rid of their Park Hoppers.
2 Day Park Hoppers have always been the hardest to get ahold of!
