Yes, your able to get a real ID as a walk in. Just have the proper items for the real ID and when its your turn they give you the option.
You have to sign in and get on a waiting list
Yes, I recommend getting an appointment because there seems to be more demand for pictures than other types of things at the DMV. Take the appropriate documents. And see if you can get the form on line and fill it out ahead of time. All these will decrease your wait time. I felt if I'd had the form already done it would put me ahead. So go early and get that form done before your appointment.
