All that to say, why not just really work on enforcing the high risk areas - inside stores, queues, and even on the rides itself. I think the average person that's going to try to do the right thing could suck it up, even in the heat, and keep it on all day in those areas. And it would be easier for parents to enforce their kids in those areas rather than constantly checking the 3 year old on the stroller, etc. Then, when they're strolling through the park otherwise (and drinking lots of water anyway), they don't have to worry about being accosted by the aggressive guests and the Cast Members don't have to spend their time constantly being the bad guy out in the wide open spaces. Of course, if they want to wear it in those areas, fine. But it just seems like they need a plan that can be followed and enforced where it is the highest yield.
