Where exactly IS Palau anyway?

It was the Survivor Finale last night, I tuned in just in time to see the final tribal council and was disappointed to see Ian wasn’t in the final two, and I don’t really know exactly what happened that he got voted out – someone enlighten me. I was rooting for him, not really for any reason other than the fact that he is a penn stater like me, and he is a dolphin trainer – how fun is that? But, I’m not mad, because I liked Tom too, and was glad to see the firefighter from NY win the big prize. Is it just me, or was that a Katie stunt double in the live finale? She didn’t look anything like the girl that was getting totally slaughtered during the final tribal council.
