Question about Miami DMV for Drivers License Renewal

Hi,

My sis has to renew her drivers license (ordinary non commercial) in person, and it's expiring in 6 weeks. She had a 10 year license. However, there's no appointments available for until the middle of May. However, this is only a partial list of the many DMVs available - most DMVs don't say "Appointments".

I'm looking at the list of DMVs - especially the one on 15555 Biscayne Blvd - the ones that don't say "Appointments", are they walks-in only? Can we just go there wit her and wait? If so, we'd like to go in the afternoon. If it closes at 4, can I go there at 3? Or need to go earlier, like 12?

Also - does anyone know how the driving exam for renewals goes?
