Anyway, the UI is different now and in big type it says "Due Now" with the resort fee mentioned under that. I personally didn't find it confusing before, but it's now quite clear.
But hotels don't charge you a parking fee if you don't park there. Whereas they won't let you check into the hotel unless you pay the "resort fee".
Again I have no problem with hotels charging part of the price upon check in, but it's super unethical for Hotel Tonight to:
A) advertise hotels based on prices you can't actually get a room for
B) do everything possible to hide the fact that the hotel won't actually let you check in without paying an additional fee (sometimes hundreds of dollars) until you've already made a large non-refundable payment
C) lie to people's credit card companies when they dispute the charges
This isn't a legitimate business, it's a criminal enterprise.
This isn't a difficult concept.
