I traveled to Miami in May, went through a long line and didn't get the Pfizer shot as they were checking people :( I wouldn't want to spend so much money flying there without a guarantee. Anyways, I will probably be able to get something (looking for a 3rd Pfizer shot), I just don't like to depend on getting lucky.
