Just for clarification:
1) The earning rate for Gold/Platinum/Diamond is 5 / 5.75 / 6.5 points respectively per USD is that correct? or is it capped at 5 points per 1 USD?
2) To earn points for dinning/spa-ing, I just present my Hyatt Gold Passport Card after dinning/spa-ing during the bill and I am entitled to the points? Or can I just give my Gold Passport number.
