True, resort fees are not part of your pre-paid fees, but they are added costs that should be considered when booking.
I will try to post some screen shots of the places I have encountered with the extraordinary "taxes and fees" amounts, but I am a noob and need 5 posts before I can post pictures.
My very extensive searches over the last few weeks have almost always revealed that those *coughoverinflated* fees show up on lower level/quality hotels touting incredibly good miles. Higher quality hotels with expected room rates, or lower quality hotels with lower miles awarded usually track with correct - just taxes- fees.
