DH and I stayed there several times and enjoyed it very much. I 've never stayed at BWV (actually we are staying there for the first time this Jan.) but as the previous poster said, POR does not have the same amenities/space that a deluxe resort has. That aside, I think POR is just lovely. Our rooms were always immaculate, and the grounds are beautifully landscaped. I prefer the "rustic coziness" of the alligator bayou section, but the mansion area is also nice, just a bit more "formal".
Enjoy your vacation!
PS:I've never stayed in a King room, so I'm not sure about the trundle bed.
