Second, I am seeing some pretty surprising (error?) deals. For example a tier 4 hotel is 50,000 points per night, so a 6 night stay would be 300,000 points. Often, hotels will include cash co-pays for upgrades, club level, etc. So, a base room would be 300k points; an upgraded view might be 300k + $100 per night; a suite would be 300k + $500 per night, whatever.
