Driving home if sick is probably the best solution, staying in Florida and having the ability to properly isolate yourself for the duration of your illness anywhere that isn’t home would be so difficult. And imagine if that person ended up so sick for weeks, months, before they could drive themselves back home.
Getting home ASAP is probably best for anyone who gets sick on vacation. It is scary to think about all the spots they could expose people along the way, but probably the least bad of all the choices (except not traveling lol, but we won’t go there). Really, the people who we all need to be most concerned about no matter where we live are those who are sick but drag their feet in isolating themselves for a variety of reasons (I thought I was fine, I just needed to ______, etc.) In regards to Disney, you know there’s going to be those jerks who need to get their last park day in, despite not feeling great, then oopsies next day turns out they’re positive.
