Let me come to Marriott's defense here though I'm probably in the minority of views here. I think Marriott should respect the ownership rights of all owners. Marriott can't simply go around and start kicking out owners who are not responsibly parenting their children, which appears to be the case during the so-called Hell Week. Unfortunately, as owners in a fractional share piece of real estate, all of us are stuck with each other -- and we don't have a choice in our timeshare ownership neighbors. Sometimes we get lucky and meet people we really like who are courteous and respectful -- from my personal observations, I've many encountered many more decent people than "jerks" in the resorts I've stayed over the years. I would not want Marriott to start acting as the manners and parenting police; that's not their job.
Moreover, for this particular situation, Marriott probably does not want to get the push-back it might receive from taking strong aggressive action against an organization that might claim that its being unfairly targeted for rude and offensive behavior. Just think about it for a moment. Here, in TUG, it took the intervention of the Tug Administrator to identify the group by its own name because of the apparent sensitivity others might have over naming that group/organization, and yet we implore Marriott to be aggressive against this group and incur potential backlash and push-back from those who might exhibit equal sensitivity towards this organization!
Unless this group is causing property damage to the resort or engaging in illegal conduct, which might be grounds for Marriott to terminate ownership, I'm afraid other owners of Hell Week are stuck with this group. (And we don't know if this "group" owns timeshare interests in group name or individual members of the group own the timeshare interest; in each case, there might be differing legal implications). However, the fact that Marriott is now requiring a Surety Bond with this group is a very good sign that Marriott is laying the foundation for taking appropriate action if the group starts vandalizing or damaging resort property.
For me, I still believe the leadership of the organization needs to held accountable. I just can't fathom the idea that it condones this behavior. I'd shame it relentlessly over this. And ensure Marriott knows about it too because this is actually damaging to the Marriott brand and timeshares in general! I'd call up the major newspapers in major media markets about this situation and suggest that they send one of their reporters to Aruba in January to investigate Hell Week -- I'm sure someone sees value in such a story.
Or better yet, next time, next year, get the cameras out and show the rude behavior -- this could go viral on YouTube! I bet you'll get someone's attention over this.
