Have you used any of the hand held fans? Some are better than others. The majority are sold by Chinese companies with tens of thousands of reviews.
As I’ve mentioned before, I’m at Disneyland a couple times a week. Disneyland is not as hot as WDW, but I carry a handheld fan with me most of the year. Personally, I have this one. I’m not sure it is the best available, but I can give my feedback. It is sturdy and relatively lightweight. I’ve tried some that were smaller, but they were flimsy and didn’t help when it was hot. This one charges quickly and holds its charge for several days of use. It cools better than the other handheld fans I’ve tried.
I’m not telling you to get the one that I have, just pointing out to be cautious when there are an unusually high number of reviews.
I’ve mentioned this previously and will mention it again. With Amazon’s dynamic pricing, check www.camelcamelcamel.com to see if you are buying something when the price is high or low.
