I must be lucky then...I rent at LGA fairly often and I have not had any problems with the bus. I did have to wait about 5 minutes when I returned the car last week and that seemed longer than usual for me. I rented it from 32nd Street (across from the Garden) and got a brand new car (67 miles). I'll be renting in Albany, NY every 1-2 weeks for the foreseeable future now so we'll see how that goes. Cheers!
