Despite fairly extensive internet searching I cannot come up with a better way to get from LaGuardia airport to (or at least near) Shelter Island than to either:
(1) take a shuttle from LGA to JFK, the train from JFK to Jamaica station, then the LIRR to Greenport, and a ferry over to Shelter Island; or
(2) take a taxi from LGA to a bus stop in Queens, then the Hampton Jitney to (? not sure where would be the best).
I feel sure someone has a better suggestion for me. I have no experience traveling in this area, and am just randomly looking at stuff on the internet. Please help!! I don't want it to cost a fortune (as in limo service from the airport) or take forever (which option #1 seems to).
Your suggestions will be greatly appreciated.
