Anyone ever done this? We currently have a one way rental BOS to MHT, both National locations, using a free day. If possible we would like to return to an Enterprise neighborhood location. We called National 800 number, they told us yes it can be done but it is up to the location where we rented and we'd have to ask them. So we called BOS, no one answered the phone. Called 800 number back they told us to try calling BOS again. Tried again, no answer. Then called the neighborhood location where we wanted to return to and they said yes we could do it, just bring in the car and they would call National and have the return location changed. So we asked if there would be a drop charge. We were hoping no since we were using a free day. He didn't know. Called BOS back they said we could not return to a neighborhood location, only to Enterprise airport locations. Has anyone ever done this? Is it possible?
