I can't remember which level we parked on, maybe 6. We parked near the elevator but didn't realize until we got our luggage out of the car that there were a few steps up to the elevator, but we managed it. Not sure how to get to the parking spots that were level with the elevator, maybe had to start back down. Anyway, directions to the garage were confusing - google maps was directing us to the wrong side of the building. What worked for us was to come down Charles Street to Harmony Circle and get onto Andrew Higgins Blvd. Turn left onto S.Peters St., then right onto S. Diamond St. You can drop your passenger and luggage on Diamond St. at the entrance door to the garage building. That is where the shuttle will pick you up. Then turn right onto Convention Center Blvd. and right into the garage. Someone will be at the top of the ramp to take your paperwork and direct you. It was really very easy.
