Thanks very much for the replies.
When I posted earlier, I had less than 5000 miles in my GP account so I could not see the actual booking options for each property. I was simply going off of the chart listed here.
I've just transferred some more miles into my GP account and I now see that indeed there is no "Regency/Grand Club" option when attempting to book an award stay at the PH.
So if I understand correctly, were I to book a Gold Passport Award room @ 22,000 points, as a basic Gold Level member, breakfast would not be included. Are there any amenities @ the PH beyond the coffee/tea service that I could expect in this booking category?
