We just go through CRO. No risk in dealing with a stranger that way. We always stay two weekends and we like daily maid service. We also got the Best Rate AP rate this time. By the time I calculate the cost of renting points for two weekends (very pricey!), add in the cost for daily maid service (which we would have to pay extra for if we rented points), consider the risks inherent in dealing with a stranger (though I realize most people have a good experience) and factor in the Best Rate discount -- or today's code rate, we figure it comes out about the same.
