Take the Tollway southbound to the tollway booths. There are two choices: one is to exit to the right to "I-35E SOUTH" and follow the signs. See "From 35E North of Downtown Dallas" for further instructions.
For those more familiar with Dallas, above the left-hand lanes there is a sign that says "HARRY HINES/DOWNTOWN". Stay in the left-hand lanes. After it splits off from the tollway and other lanes merge on from the right, move over into the right-hand lane. There will be a sign that says "WEST END". This lane curves to the right. You are now on Field Street headed southbound. There will be a light at Woodall Rodgers Freeway. Continue under the freeway going south.
Field Street: There are four lights on Field Street that you need to go through. The 1st is at the bridge under the highway. The 2nd is where Griffin splits off to the right. The 3rd is at Ross Avenue. The 4th is at San Jacinto. The next street is Patterson. Turn right and immediately turn left into the Renaissance Tower parking garage.
Park anywhere above the 3rd floor. Once parked, take the elevator to level B (the basement). Turn right out of the elevator bay and go through the glass doors. Turn right immediately. Turn left at the end of the hall and go to the marble-floored lobby area. Go up the escalator to the Ground level. Go to the elevator bay marked 34-44. We are on 38.
