You're going to be driving through the streets of Brooklyn to get to Floyd Bennett Field. It can be done but it's not something I'd recommend or want to do myself. Liberty Harbor is pricey and no frills, but the location is everything. You are RIGHT THERE. The streets getting to Liberty Harbor are narrow and congested but not as bad as in the city. I've seen every size and type RV in there. Any place else is going to be at least an hour's ride each way.
