Well, at this point, I'm thinking that the larger, more expensive resorts (Gaylord, etc., avail. on PL/HW) are probably going to have their own dedicated shuttles. From what I understand, a third-party shuttle service is usually shared by the less highly ranked lodgings. The other best option, I think, is for you to look at the Downtown Disney hotels. They do share the shuttles, and as with the resorts mentioned above, they park farther away from the gates of the parks; however, I do recall the shuttles running fairly often. You will find at least a few of these DD hotels also popping up on PL. Ergo, if it were me, AND I were absolutely stuck on going to Disney at this time, I would try to PL it. I also think a cancellable back-up should be made yesterday. ;0) P.S. Since you're on a strict budget, make sure to allow for resort and self-parking fees at the resorts, if you decide to bid for them (you'd have the same expense if you booked these conventionally anyway).
