The zipcars are right on campus, parked in front of Keefe. They are definitely convenient as you can rent them either by the hour or day. The fee includes gas, tolls and insurance. I think the maximum daily mileage is 160 and I believe it runs about $65 for 24 hours. My daughter rented one for a med school interview to Dartmouth which is 100 miles each way so she did a 2 day thing so she would have the mileage covered. For going say for instance to the Holyoke Mall which is probably 20 miles, if you just rent one for say 4 hours and have a few friends go with you, it is a great deal. As I mentioned to you before, freshman are not allowed cars on campus, so the zipcar thing is a great option for short trips, but the PVTA will take you anywhere in the Amherst/Northhampton area although being a longer trip.
