TotB - Needing to create stronger motivations to go to and stick with the Castle

[Helaman]

The motivations to go there are sort of weak and to stay and finish out the castle in the face of some nasty NASTY combat encounters is limited.

Given some freedom to tweak, add clues and do some minor re-writes, how would you strengthen the characters motivation to go there and get to the end?

It might be easier to answer if we knew why there's a lack of motivation in your group, but anyway, check out this thread which addressed the problem: http://paizo.com/forums/dmtz5wn7?Player-Character-Motivation-SPOILERS

No group as yet, planning for the campaign and like to have my ducks in a row so to speak, so interested in whatever you or the others can throw in... will check the link.
