Ouch, I figure that at something less than 0.5 cpm most places (probably less by the time you add taxes not covered by the certificate). Their sole hotel partner is pretty bad too. 25,000 miles is a pretty terrible deal for any Radisson other than the one in SF which is where I live and thus have little use for a hotel. Has anyone tried writing off FF miles when you donate them? How do you document the value?
