Anyway, the reason for the post was that I don't remember ever having to buy points to use points for a room in the past and wanted to make sure I was not misreading the "data".
That does seem odd, but I just looked at the IHG website and they disclose it up front:
'If you’re booking with Points & Cash, buy the points you need. If you’re using all points, skip to the next step.'Maybe their reservation system can't split the payment. Dollars and points might be like paying with dollars and Euros, and some desk clerks might find that tricky.
As for those points, merchants pay about 3% to process credit card transactions, and hotel franchisees pay even more when you rent a room. Since those fees are built into prices, why not get some money back? Many credit cards return as much as 2% in cash, and hotels and airlines have generous rewards programs.
I don't travel that much, but 3 of my last 4 rooms were free, and the other one cost me less than $70. That offsets some of the inflated prices I paid on a ride last summer!
