Anyone recently done a license renewal in person?

I'm ineligible for online renewal since they only let you renew your DL every other expiration so I need to go in for this one. I'm trying to figure out what the smoothest approach is for this now with least amount of hassle under the current climate. I do have a real ID license.

Unless I am missing something when I select, let's say, Margate from the appointment portal I can only look at appointments 2 months out into April. I can see the times, but they are all gray and unclickable. I'm assuming that means they are all unavailable?

Can I drive to a less populated area's location to our north? I don't see an option to select locations outside of Broward or Miami in the portal.

Last, if I do manage to snag an appointment, what is the protocol like at the DMV? I haven't been in one in I think over 15 years? Do I just walk inside if I have an appointment or is there a line out the door I need to wait in shared with walk up customers?
