Hyatt Arlington had 1W bonus listed as an amenity option, but the clerk wasn't able to enter it when I checked in. When I checked out this morning, a different clerk entered the G1 bonus instead, and that's what is printed on my receipt. I hope it takes.
The GH Washington D.C. did not offer the 1,000 points bonus on the list of amenities at check in just now. I asked and the clerk said he would enter it into my record. I'll see what it says on my check-out receipt tomorrow.
