Several months ago we booked a stay at JW Marriott in Panama using Reward points. The trip is now two weeks away and we were just notified the hotel is cancelling our reservation to book a large party. This is a vacation involving international airline reservations and we cannot reschedule. We have been treated rudely and no one at the hotel or Marriott Rewards by telephone is helping us. I have emailed customer care as has been suggested. I am shocked after so many years as a Marriott customer. Can someone help?
