In case anyone is interested in the outcome and/or for future reference, I ended up canceling the Crowne Plaza on my own and rebooking into the IC. After a couple back and forths, I was told to cancel, re-book at the IC, and then my account will be credited with the point difference. The property manager and reservations department reps at the Crowne Plaza were very educated and helpful in the responses that I received. But as was pointed out above, I had to push in order to get an answer and the end result. I'm very happy with result.
