Although I understand conversions, I've found the general rule to be that the best value for points/miles earned is in the program you earned (or bought) them through. I even believe that about Wyndham and Sheraton, the two darlings for conversion from hotel points to miles.

I assume a lot of folks don't get the viewpoint that after the flyin', there's gonna be some stayin'. Of course, if you're young, miles/points are few, and at your destination you can stay in a hostel/with friends, then hotel points are of little benefit. But, once you've got a significant other/family/little maturity, you're generally going to be staying in places you must pay for, and many times, the cost once you're on the ground vastly exceeds any flight cost you might have.

For instance, even with high airfares this summer, I could get to northern California for $500 or less, but if I'm staying a week in a relatively cheap, safe, clean place that's not in San Francisco (EconoLodge, not a Park Hyatt), I'll match that $500. Raise the standard of the lodging at all, and I'll get to $1000 very quickly. Make the destination San Francisco itself, and I'd be hard pressed to keep the hotel cost under $1400 (don't be fooled by cheap weekend $99 rooms, you'll pay $250 or more for a lot of places during the week). New York, Chicago, Miami, LA, Paris, London, Rome--all places where you can exceed those numbers.

I'm sure I miss some sterling conversion opportunities, but I've found it a fairly safe general rule that the best use of almost any earned/bought mile/point is in the original program. There are not many 9000 point properties in the Radisson portfolio, but I know of one on International Drive in Orlando where 63K points would get you a room for a week that would cost you at least $720 otherwise.

You know what 36K US miles gets me if I want to go from ORF to MCO for certain dates in August? The need to buy 1.5K more miles. And that's only because I get a 5K discount as a Barclay's US Mastercard holder. I can buy the flight for $292 outright.

Sure, that's kind of a tricked up example, but it illustrates the need to consider what you could use hotel points for rather than just blindly asking about conversion rates. 150K Radisson points can definitely get you three nights in an expensive overseas property, returning a much higher value than 36K US miles.
