I had emailed Sheraton's Vistana Villages through the website for Sheraton, there was a link on their site for ownership...I emailed them and inquired as if I were interested in possibly buying and wanted to know if there were any offers...they contacted me and we got a one bedroom villa for 3 nights, plus two theme park attaction tickets for $199.00. We did have to sit through the 90 minute presentation though, which turned into longer because my foolish DH was interested in it, so they kept us there a long time before they believed we meant NO the 1st time. It was a beautiful resort and in a great location.
Good luck!
