I haven't used the CC for any of the options and have only been to a couple of the resorts. General concensus is that these, for the most part, are world class resorts. The Grand in MI, Stein Erickson Lodge, Arizona Biltmore, the 2 HI resorts, and so on. All you have to do is turn on the travel chanel and you're likely to see one of them reviewed. I've seen 6 of them mentioned within the last 2 weeks and have seen a whole show on 2 of them. These should be easy resorts to get info on. I'd agree that a collection of reviews on the resorts might be helpful for some. MS should be able to send you that type of info on any you have interest in. I can only think of one (maybe 2) that I'd have concerns about the resort.
The resorts are not the problem, the points costs in the problem. I guess that's another thread so I'll let it go at present. Much has been said about Keystone, the HI resorts, The Grand, The dude ranch and SF choices, do a search. If there's something you don't find, ask and maybe others will know something to help.
