To return a car to Thrifty at Logan, is the Tomahawk address the one to use for GPS? ALSO, I know it can vary, but how long is the typical process time to process the drop off and be driven by your bus to the International terminal at Logan? Thx

I agree with george.... shuttle depends on how packed it already is or not.

The Tomahawk address is close, but definitely rely on the actual signs on the road to get to the return center. Based on my experience it usually takes 5~10 minutes to get back to the terminal.
