This is not a bad idea and I rarely carry over RCs from one trip to a future trip. The only exception was when I was saving up RCs for the long New Year's weekend. When New Year's Weekend was over and my room charges were all paid, I converted the remaining RCs to free play and cashed out a little "going home money."
I recalled when Caesars was bought out by Harrah's and my host then advised me to take all of my comp dollars (and I had well over a thousand dollars worth) and use them in the gift shops. That's what I did buying clothing, cologne, bathrobes, small electronics. He told me it wasn't clear what would happen to them in the buy-out.
It's a more precarious situation now -- and has been since the bankruptcy was filed. Even though Caesars management said points would be protected there was no guarantee then and there isn't now.
Right now in my TR account I have $9 worth of RCs.
I think it would be prudent for every player in TR not to carry over too many RCs regardless if TR and casinos are sold or not.
