Yep! Stayed at the Marriott Phuket Mai Khao Beach using my friend's timeshare. Since I wasn't a member, I was "invited" to listen to a presentation. The whole thing only took 90 minutes and the reward I chose was 2 free rounds of golf at Mission Hills in Phuket. Since I was planning on playing there anyways, I was happy to sit there for 90 minutes and save $300+ USD!
