I always do the automatic wash and that's what I did today! It has vacuum bays and a dispenser for ammenities should you need something. I have not used the self-serve bays so I can not attest to those.
They have 2 touch-free automatic bays and a variety of washes to chose from. I got the Ultimate Wash for $10. I loved it. It does Undercarriage, foam clean, high pressure wash, clear coat, no-drip rinse, air dry. Just what I needed to clean all the pollen and bird crap off my van.
I can't complain!
