We like flying out of TF Green. I will warn you NOT to park at a place called BEST VALUE parking. It is right around the corner from the airport.
Last February, I prepaid for parking there for a 10 day trip. We checked in, parked our car and left on our flight. 10 days later we arrived back at 10:00 p, to find the entire side of our smashed in. It turns out, that FIVE MINUTES after we left 10 days earlier, they went to move the car to another location...which they never mentioned and the person driving got into an accident with the car being broadsided. They never called us to let us know!!!
There was a police report with the time and date on it and the accident literally happened five minutes after dropped the car off.
When we saw the car, the guy working there was like...oh sorry....yeah we had a little problem. I had to wait in 20 degrees for the police to come. The company then turned around and said it wasn't their responsibility since they thought the other person was a t fault. We spent months trying to get them to pay for the repairs....which they only did after we got a lawyer involved.
Lesson learned....pay the extra for the airport lot. That way your car stays in the same spot you left it.
Hope this helps!!
