Yes I think this is very likely the way they will go. Will be interesting to see if Uni, Sea World and Disney can coordinate on this and make it standard practice across the Central Florida parks.Let’s not forget, the CDC has already said vaccinated adults and their unvaccinated children can be out and about without masks. Disney can remove the outdoor mask mandate and tell people to still distance and stay in groups of no more than x people (8 people? 3 family groups? Their choice. Latter most likely) and be in line with CDC policy, FL state law, and (soon) Orange County guidance.
Indoors will take longer.
