Did this actually happen to your friends or to friends of theirs?
The reason I ask is because about ten or so years ago I was told almost the exact same story by a woman I met at the Towers pool only she said it happened to her friends at the Sapphire. The dollar amount as I recall was a little higher, $15000.00 sounds familiar, and it was a $10,0000.00 watch but basically the same other details.
Not saying this is the same case but I took it as an urban legend then and to this day I would question why someone would have had that much cash on hand and were staying in a timeshare, but that's just my take on an old memory.
