Julia -- As I pointed out in my post, the GP Customer Service folks are very responsive to my emails, and corrections are quickly made. The weakness is: 1) More often than not, the airline bonus is not posted to my account automatically -- eventhough I request it at check-in, and 2) Your internet site does not provide detail of points posted for each stay until the statement is printed, thus, like Pino, I do not find an error until I get a paper statement months later.
Shadow -- you should get GP points, plus a 300 point airline partner bonus if you fly to/from a Hyatt location.
