Most people argue about mask requirements in WDW, which is of course a very important subject. There is one point, however, that I haven't given much thought until recently: flying health requirements. Suppose the kids get a cough when it's time to fly. Kids get coughs all the time, and normally, that's not a big deal, but now it's suddenly a huge warning sign that will ban the whole family from flights. Sometimes my kids' coughs can last a week or 2, so then my trip will be delayed or completely ruined. Even worse, this can happen on the return trip so that I will be stuck at WDW, not knowing when I can come back. One can buy insurance to cover the finances, but the vacation is ruined as a result. Note to self: cannot fly anywhere till airlines no longer have health rules.
