I am finding these nice PDF’s They have some good info to help you with huge Dreamforce experience.
I will update this post when more become available.
Dreamforce Whats New 12 – This file name is a bit misleading. This has a ton of info in it including maps, agendas, how-to, and other great info.
Dreamforce ’12 Programs and Access FAQ – Good info on what the different types of tickets give you access to.
Useful Information – As the name says this has useful Dreamforce information, including free shuttle routes.
DF12 Campus Map – With 8 (yes eight) locations you want to get around to at Dreamforce this map will come in handy.
