I went to Animal Kingdom with an non-theme park, Avatar fan, who has been dying to finally check out the land. We couldn't do FoP but intend to this week. Some comments from him:
Land looks beautiful but nothing to really do after the initial awe of the first viewing. The nighttime was great, but "too damn dark".
The store sucked other than a few cool pieces of merch.
He did River Journey. He liked it but did say the FP helped his positive review. "If I had waited 2 hours for that, I would've asked for my money back."
