I'm not so sure about this. They now have the CDC largely advocating for the elimination of outdoor mask usage. Having to wear a mask in the Florida summer heat is going to be a deal breaker for some people and the elimination of the outdoor mask policy very well could result in more bookings.
It may be administratively inconvenient, but if the flip side is higher attendance I imagine they will do it.
I have a trip planned at the end of July and I would be very surprised if I'm required to wear a mask outdoors.
