Of the top of my head, I know Kelley Wentworth turned it down because she didn't want to return so soon after Cambodia, which I assume is why Ciera is there instead - and then there were probably the usual suspects of Parvati etc who they'd ask anyway, plus people like Joe (Anglim, not Del Campo, as if I even needed to specify) who I also think turned it down

Then there were a helluva lot of people who were apparently cut: Alexis Maxwell, Carolyn, Chelsea, Danni, Earl, John Cody, Jon Misch, Penner, LJ, Marty, Mike Holloway, Thirdpersonica, Natalies Anderson and Bolton, Peter Baggenstos, Sabrina and Sophie Clarke (Natalie Anderson in particular was said to have been cut for Sierra)
