Pittsburgh Accommodations

If you are planning to arrive in Pittsburgh over the weekend preceding the retreat, PDL has several rooms on hold at each of the hotels listed below. When you call the hotel to make reservations, tell them that you'd like a room booked for the PDL Retreat (or quote the appropriate code listed below). You may also book extra nights at the preferred rate if you request them at the time of your booking.

Your room reservations for the nights of the Retreat itself (Oct. 26 and 27) will be taken care of by us, so you will only need a room at one of the following hotels if you are arriving early and/or staying past the Retreat.

Please make your reservations as early as possible, as there are several Pittsburgh events that may also make rooms scarce.

TIP: There have been times when your corporate rate beats the rate we were able to secure.

Getting to and from the Airport

Please make your own transportation arrangements from the airport to your hotel / CMU. There are several options available for getting to and from the airport:

Uber Pittsburgh - learn more

Uber is a mobile application that connects you with a driver at the push of a button.Drivers arrive curbside in just minutes, and you can track the arrival of your ride. Payment is seamlessly billed to your credit card, PayPal account, or Google Wallet at the end of your trip—no need to tip.

You can download the Uber app using the following links:
iTunes App Store, Google Play Store, or Blackberry App World.

Rental Car: Available at the airport from all the major companies (not really recommended for the Retreat since we depart CMU to go to a resort that is about two hours away).

Taxi Service (~$60 each way)

The following driver services cost ~$65 dollars one way (includes tip). The drivers do accept credit card payments. If you want Karen to arrange this for you, please make sure she has your full flight info (date / time / flight number) and your cell phone number.

Airport Sedan Service (Larry Waite)
Advance reservations are required, ~$60 each way
Contact Larry Waite, 412-401-LIMO (5466)

Getting to CMU from Your Hotel

Most of the hotels have shuttle transportation to CMU available. This is NOT a direct shuttle to CMU and will make other stops in Oakland based on customer needs. If you do choose to use the hotel shuttle, please request that you be dropped off at the RMCIC Building.



Directions to the Singleton Room in Roberts Hall

The Singleton Room, surrounded by the Seagate Technology Atrium, is located on the fourth floor of Roberts Engineering Hall (REH). REH is behind and connected to Hamerschlag Hall and may be approached from two directions:

Through Hamerschlag Hall
Enter the front doors of Hamerschlag Hall from the campus mall. (Hamerschlag is the building with the cupola on top at the west end of campus.) Proceed to the staircase or the elevator at the end of HH first floor. Go down to level "B." Follow signs to REH. You will enter the Atrium next to Singleton.

From outside REH
Pass in front of Scaife Hall and follow the sidewalk on to the covered walkway above the service road. Proceed through the door into REH. The Singleton room will be on your left.

Campus Maps



While we assume most of you will use the shuttle PDL will provide, there are parking machines on Schenley Drive, Frew Street, and Tech Street which are all very near to Roberts Hall. They accept currency and credit cards; it is $3.00 / hour and uses your license plate as the timing factor. If you prefer, I should be able to secure a parking pass for you at the RMCIC Building Garage - P4 on the general campus map (closest) or the East Campus Garage - P7 on the map (further walk but more familiar to some of our guests). Some past attendees have also used the parking lot at the nearby Carnegie Museum (also shown on the map).

If you park in one of the above mentioned areas, particularly Schenley Drive, Frew Street, or Tech Street, please see this map for the Roberts Hall entry location/drop-off point or this map of campus.

Other Handy Maps

Bedford Springs Resort

Bedford Springs Resort is a four season, historically significant destination located on 2,200-acres. It began welcoming guests over 200 years ago when the mineral springs of Bedford Springs, PA became known as a source of rejuvenation. The resort is approximately 90 miles east of Pittsburgh.

CMU Retreat attendees and guests will travel to Bedford Springs on Monday, October 26 and return Wednesday, October 28. We will provide bus transportation to the resort on Monday and back to Pittsburgh and the Pittsburgh International airport on Wednesday afternoon.

Participants of the retreat will be members of the PDL Consortium and invited guests. Information on becoming a member of the consortium is available from Karen Lindenfelser, Bill Courtright (PDL Executive Director), or Greg Ganger (PDL Director).
