Hyatt Regency Pittsburgh Hotel Parking
When entering the airport from the Highway, immediately move to the left lane. You will take the Longterm Parking “Exit”.

When you come to the gate, pull a ticket and proceed to the end of that lane to the stop sign. You will be facing the moving walkway. If you find a spot nearby, park there, enter the moving walkway and you can access the Hotel Lobby from there.

If not, make your way around to the other side of the moving walkway and park behind the hotel in 2C or 4C area. You will keep your ticket that you pulled to enter the lot in your car.
At the meeting, you will be given a voucher. When departing the parking lot, enter your original ticket first (should be blue on the back side) and then enter the voucher (should be white on the back side) and that will cover the event parking charges.
