So, to make this long story a short story.... We visited Sheraton Vistana in September via an exchange and loved it. So, We bought an odd EOY on eBay for $1. The posting said our first available week was in 2017. Today we received a letter from Starwood saying they confirmed our ownership and to call in to check that there's no additional dues or taxes. We didn't expect any, and confirmed there wasn't. But, to our surprise the 2015 week was still available. We plan on depositing that into II and using it next year for a week in Aruba at Marriott. Bottom line, we got a week in Aruba for the cost of an exchange plus $1.00. Sweet!
