And yet another rich offer for your choice of plastic. This has to be the richest offer yet for any of the Hilton HHonors credit cards — up to 50,000 bonus points (up to five free nights depending upon hotel category choice). Earn 10,000 Hilton HHonors bonus points with your first purchase, earn an additional 10,000 Hilton HHonors bonus points (catch: 2,500 Hilton HHonors bonus points for each of your first four stays at any Hilton Hotel), then earn 30,000 additional bonus points when you spend $5,000 by Mar. 31, 2007. This should all be easy for any of you.
