So here's the thing though... this is never going to be over. I mean yes, the urgency of the pandemic will end some day, but Covid is going to be with us forever, per the forecast. They expect it will become a seasonal issue like influenza, requiring an annual vaccine, and that we may see pocket epidemics.
I think 12+ will be available, but I don't think anyone is predicting under 12 being available that soon unfortunately since they are literally JUST starting to trial children in the 5-11 range. Trials in children take longer than adults.
As for the original question... it will basically depend on case numbers. If they're low, then yes. We'll be driving to Florida anyways, so much less risk that way, and they would absolutely be willing to wear a mask when in line/indoors (assuming masks are no longer required by the time we travel), and the risk of outdoor transmission in Florida in summer is extremely low.
