I checked a while back and was advised to wait and see what the tunnel situation is like closer to our trip. We are arriving about 4pm on a Thurs. afternoon (9/21) and heading to Hyannis. We haven't reserved a car yet. Should we get one in Boston and muddle through rush hour and the complicated looking directions I've seen or maybe take the train a ways and then pick up a car. If so, are there are car rentals near train stops in the right direction?
