I called Hhonors and they said they can only post the folio that is sent to them by the hotel. The folio they got said $44, but I have the original that is $109, so I think I'll just send it to them and bypass the hotel.

I had to make another reservation for an upcoming stay, and this time the park and fly rate is $99, and the "Best available" room-only rate is $89, so I guess in theory parking should be $10 (it's a great bargain in any case, it's just them I'm trying to get enough points for a free stay and every little bit helps).
