I would love to know if there is an option as well.
I have looked up long term parking on the Airport website and all they seem to show is the airport parking at $24/day - it is the same price as short term parking. I have flown for work and used this - be careful though - if you are there more than 6 hours into a day they charge you for a full day
Where are you coming from? I know that CT Limo has a shuttle for $110 RT. There is another company called Red Dot I think as well.
Also, depending on the number of you, you might want to use a car service. I think that private car service from Stamford, CT runs about $150 a way. Depending on the number or people, it might be worth it to get private service.
If anyone knows of a cheaper parking place, I would LOVE to hear of it. It would be great information for me!!
