I've searched on this topic in FT and haven't come across anything that useful. I'm looking for off-airport parking rates for Providence (PVD). I've come across several places that charge $12-16 day, with a couple various discounts for AAA or internet rates. I also know that the airport itself charges $11/day for parking in the economy lot.

The question is this: What are the cheapest options for long weekend parking for the PVD airport?
