Julia, could you explain the airline partner bonus to me?

I just checked out of the Hyatt Houston (downtown) this morning & asked about my airline partner miles. The clerk said you get either GP points or miles, not both. When I asked for a better explanation, I was told that's the way it always has been. Has something changed?

Since I needed to get to the airport for an early flight, I decided not to question it any further. BTW, that property only has video check-out available after 6AM, so any earlier you must stand in line to check-out. There were 8 people in line with 2 desk clerks at 5:45am.
