If you go on the website, you can check wait times and if there's slots still available, you can do an online check-in to give yourself time to get there
Walk in Clinics are open until 7:30pm. If at all possible try to check in by 7pm, but if you arrive at the check in desk before 7:30 you should be seen. You can also Reserve a check in time online. This is not an appointment, but holds your place in line for when you arrive to check in for a walk in appointment.
Check there website and see if they have any spots open. You can also check the silver lake walk in, its only a 10min drive from the mill creek walk in.
