We are flying to Boston at the end of August (Saturday 30th) and need to be in NYC on Wednesday 3rd for the Open tennis. Our plan is therefore to arrive in NYC on the 2nd for some early evening sightseeing in Manhattan from our base in Queens. We have the first two nights of our trip booked to stay in a Boston and so need a plan for travel between the two. We had initially decided to stay a night somewhere en route (Monday 1st) but have not booked anything yet and have just discovered that this is the Labor Day holiday, which will presumably mean it is extremely busy?! Ideally, we will still do a stopover somewhere to break up the journey but need to decide how best to travel and to get an idea of how badly the fact that it is Labor Day is likely to impact our Monday and Tuesday travel plans? We would ideally like to see Cape Cod and to stop at a couple of the towns on the way such as Newport, Mystic and New Haven but would be open to any suggestions. We'd originally looked at hiring a car in a Boston and dropping in Queens, but were also considering starting the journey from Boston by ferry and picking up a car on the way to then complete the journey by road. Looks like you can get the ferry to Provincetown but there is no car rental there? Is there an alternative? It doesn't look like there is a car ferry from Boston to Cape Cod, so we couldn't go with that plan?
Any suggestions or advice would be very welcome!
