I have a standing appt time. When I try to get in at the last minute, it's VERY rare that he has an opening. I'm glad he's a good T and has such a full schedule, but it can be frustrating not being able to get in when I need to. My standing appt time will have to change in the fall when my oldest son goes to high school, and I already feel a little anxious. Although T usually works other people around me, since I've been seeing him for so long.
