The Jamboree Duffle- will it all fit?

Honestly, I did not think that I would feel this anxious and excited about this experience.  Attributing to that feeling is the whole packing and preparation.  This is a new Jamboree concept at at new place.  Everything that you will need must fit in a Jamboree provided duffel bag.  I have watched the you tube video (http://www.youtube.com/watch?v=Gjz9ibsR9xM&noredirect=1)over and over and over---and this 49 year old Scout is struggling!  Thank goodness I can bring a small backpack. Anyone else having challenges packing?  I could use some last minute tips.  Next time you hear from me I will be at the Summit on ground at the Jamboree.  Until then, Good Scouting!
