Do you have to have an appointment or can you just walk in

You must have an appointment at all unless you have an emergency situation.

You don't necessarily need an appointment but i think it's faster that way

They are checking at the door for appointments, no appointment no entry unless there is an open space from what I was told.

It's faster if you have an appointment but not necessary

Both. You could just walk in. You don't necessarily need to have an appointment.

Online appointment only
