Are you a member of AAA? Their travel agents would help you, and there are no fees for members.

Depending on when you plan to arrive in Prov, I might be able to bring you from the airport to Mystic, but I'll want to check into my room well before Thursday evening's concert.

I won't leave Mystic until after Sunday afternoon's concert ends. Flights from the northeast US are overnight flights, and you'll need time to get to whatever airport you use and allow plenty of time to check-in and go through security, allowing for any delays. You might consider staying in Mystic Sunday night. I don't usually stay on Sunday night, but I would if we shared a room that night only. I'd make you crazy if we shared for more than one night.

Some travel sites look like they are getting ready to book tickets from Prov to Ireland for flights in March, but I don't know if that will really happen. If you can fly from Prov, I can get you to that airport on the Monday. If you fly out of Boston, I can get you to a Peter Pan motorcoach that will take you from RI right to the Boston airport, but it's not cheap. It's a for-profit company, not public transportation. Again, that would have to be on the Monday.

As far as flights from Hartford, I've never been to that airport and would be useless to advise you about it. I also won't drive there!

Are you in touch with the Milners? They might be able to tell you more. Or Geoff Kaufman might have some info. If you don't have his personal contact info, you can contact him through the seaport. Or maybe someone more helpful will add to this thread!
