OK, could be it was Hard Rock, not Planet Hollywood. I don't really remember what all the problems were..

Regarding your 4th point, SXM as a destination has always been different than many other destinations, in which people spend their whole vacation on site at their hotel. Planet Hollywood will not change that, I don't think. BUT it may get some people who otherwise would not consider SXM to come, with the potential familiarity of the brand, like at the Westin. It's an opportunity also for conventions. And then the NEXT time they come, they would stay somewhere else. Or not. Regardless there still will be local people employed at the hotel, if nothing else..
