Not at CR but it happened to us at Beach Club on our honeymoon in 2005 (which is a VERY different time than it is now LOL). We booked a standard view room and found out before we arrived that we had been upgraded to water view, by Disney. We were very excited. When we checked in at the front desk the CM gave us our room key and smiled as she said it was on the 5th floor.
The 5th floor, you say? Why that's...that's club level, isn't it? She nodded and pointed us towards the elevators. We had an amazing view of Crescent Lake and BW out our room and enjoyed the lounge every day.
