As mlob said you need to choose the FHR rate. It'll be a whole separate hotel with only FHR.
In my experience, FHR rates won't show if I have less than about 10,000 MR points in my account.
Having similar issues here. I have manually located a FHR hotel on a list with non-FHR hotels. When I click into it, it doesn't show any FHR rates.
Does this matter if I have two different Amex cards saved into my account? Or am I doing something wrong?
