Medical Transportation Needed In Seattle

I will be getting a colonoscopy this coming week at Medical center. Sedatives are used for that procedure. I will need a driver, and for this procedure the driver has to go in at check in to confirm with the nurse that they will be there when the procedure is over. The hospital can't discharge a patient recovering from sedatives to go home on their own. Check-in is at 7:30 a.m. on Wednesday the 26th, we would need to leave my place by 7 at the latest. I live in Roosevelt, a couple of miles from the hospital. The procedure takes about 2 hours, but may not start right away, so I think we will be back home by 11.
