It sounds to me like the Passporter Club is maybe the type of place where people can get together to organize guided trips? Almost like a travel agency, but for members of the board who want to meet up and get the full Disney/Passporter experience. The Concierge Level indicates that maybe this sort of thing is a little bit nicer than what us mere mortals experience when we go.
And I completely made that up...but it sure sounded good!
