Too many to count! I'd estimate 8 - 10 years of two trips per year staying at Wilderness Lodge, Yacht Club and Boardwalk Inn. If we only had the cash equivalent of DVC points, I'm sure we would be on the top 10-point list!
Even the year we bought in, we had a YC vacation planned that would have cost about $3500. Our guide helped us see the light and cancel that trip to apply it to our down payment. He was even able to get us a ressie at BCV at the two-month mark for the same time as our original trip so all worked out great!
