I stayed at the Grove Park Inn in Asheville, NC a couple of years ago using the Concierge Collection and had a great time! It's as easy to use as RCI, but you have to call MS to book and pay the $95 fee. The places in the CC are very popular, so when you decide to go, call to see what dates are available and book it then. Calling back even a day or two later may mean that the dates you wanted are no longer available(I've had that happen more than once). The only thing to keep in mind is that you can't book the CC until the contracts are signed for the new year. Sometimes this doesn't happen until January/February of that year. I've looked into staying at Mandarin Oriental, Grand Wailea in Maui, and Hotel del Coronado but they keep getting bumped in favor of other trips.
