If you check a bag then you have to go to ABE. If you just have a carry on then you can skip out on the bus ride. The bus is usually on time. I have taken it 3 times and it has been on time every trip for me. The bus leaves from C71. If you go to the P Club do not drink yourself to silly because there is not bathroom on the bus. Also even though you will have a seat assignment on your BP, there are no assigned seats.
