I have the forms I-693 ready but want to know if I can drop them off in person as I live in Orlando, or do I have to mail as per instructions?

I would call them, they are still under covid 19 rules

call them

You can call them but it's hard to get a human, I u se myUSCIS account where I make appointments as well as asking questions it's more reliable then the phone. They will call you and let you know when your appointment will be.
