Any advice for a Brit doing an American road trip?

I've just booked a 2 week trip in September with my husband to America whilst there were going to be travelling around a lot.

Were saying in new york 7th avenue for 3 nights then were getting the train down to hayannis in cape cod and staying for 3 nights again whilst there were picking up are car and after the 3 night stay travelling down to Boston for 2 nights. Next were off to North Conway for 2 nights then Bar harbor for 3 nights which I'm most excited about as it looks beautiful from what I've seen, then back to Boston again for a day before we leave to go back to England.

I've seen a couple tiktoks and done some looking online I know the obvious stuff like we have to pay city fees and driving the opposite side of the road.

I know there's a lot of Americans on this site and I wondered if any of you would have more knowledge, recommendations etc. I assume some of you have visited these places before or even possibly live there or near.

I'm also thinking of visiting Salem too as it isn't far from Boston by car when we googled it said 30mins
