I want to place an ongoing search into RCI for the Costa Linda Beach Resort #2604 for any time in the month of April. How do I find out how many TPU's are needed for this resort in April, 2013 ???? I currently have combined TPU's of 43 and I also have a week sitting with 25. I hate to break up the 43 if I only need 25 or less for this exchange. Can someone enlighten me, please??
