Pacific mentioned that he had no kids. If that changes, the Priceline hotels start to look less desirable as you cannot guarantee you will get two beds in a room (unless Priceline has changed).
I started out with HH credit cards since Mr. BOGO did not want an annual fee airline credit card. Now we have both with no annual fee. With kids, it is harder for us to accumulate enough miles to go on a family vacation and use airline miles, but there is usually a Hampton Inn or other Hilton brand wherever we go. With putting $25K on credit cards per year and reading Flyer Talk for extra tips, we have been able to get about 10-15 free nights a year for the last couple of years.
