No info on Sinclair, but if your plan/goal is to work at Cedar Point or Kings Island it is a tough year for that. They might not open. And if they do, they might not have any shows due to audience/social distancing.
Sounds like you want to be a performer, if so, as soon as you can get into a class for acting/dance/voice, do it, even if online. The performer gigs at the parks are competitive and those auditioning will have training.
I never want to talk anyone out of college, but theater training can be done outside of college (at local studios etc) and unlike many other fields, a degree is not required to get in the door (not that it’s easy. It’s hard. But your training doesn’t have to come from a university).
