Am hoping to go back to Hawaii at some point. My husband currently has 10k HH Points, and we signed up for the HH credit card, which has a bonus of 75,000 points after $3k of spending, which we just paid some college tuition. Current offer is $6 per 1,000 HH points. A Hilton hotel in Oahu normally runs about 40-50k in points per night. Worth doing or save the money?
