I complete agree that there are rude people at all levels of resorts, but I suspect that, because there are fewer people overall at the deluxe level resorts than at the larger values and moderates, the pressure cooker feeling is lessened. Looking at it as a mathematical equation, if 10 out of every 100 people is "rude" across the spectrum, and there are 2,000 people staying at BWI/BWV and 10,000 staying at POP, there will be more people overall at POP and therefore more rude people. Furthermore, because they're more closely contained, the 10 out of 100 stand out more obviously. Thinking of it as a chemical equation, at the POP there are 1,000 positively charged particles (rude people) and 9,000 neutrally charged particles (normal people) floating around in space and at BWV there are 200 positively charged particles and 1,800 neutral particles in about the same amount of space. The chances of a collision between two positively charged particles (two rude people) when you have 10,000 particles confined in a small space is, mathematically, greater than when 2,000 are inhabiting the same space.
This is only my speculation, because we've never stayed at a value or at a moderate, not because I think the people are "better behaved", much less "better overall" at the deluxe resorts, but because I don't like a lot of even the most polite people on earth around me.
OK, enough math & science. Off to celebrate Christmas eve!
