Thanks. I will call Avis to see if I can get this offer. I checked their site but it's not prominently displayed. It's well worth the cost to avoid carrying my luggage and family around such a large airport. I'll check to see if others offer this as well as I don't always travel with Avis.
AutoSlash - I lived in NYC and dealt with the horror that is LGA. I once missed a flight because of the terminal traffic.
