That's a good question. I googled the hotel collection and gets me to that portal which has quite some different low tier hotels (BW etc). I know FHR definitely does not have Four Point, not sure THC is the same deal.

Let me double check.

Now think back I don't think I'd risk the prepaid rate at THC for a potential $100 credit. The corporate flexible rate I have is the same as Amex prepaid rate.

Edit: @dw, you were right, it was Amex travel regular listing. THC has a much smaller directory.
So apparently somehow in the clicking process, I landed on the amex travel regular page.
