We have already done DC once, Williamsburg, Charleston, Savanna, St Augustine etc.  This trip is primarily to cover the NE & NY state.  Since someone said Liberty Harbor May close, we are not planning on it.  We are open to a hotel for a few days, leaving the RV in Newburgh to save transit time.  We will do the day tour from the park if offered.  We are mostly now trying to get a feel for how many days to allow for NYC downtown.  We will want to do Ellis Island & Statue of Liberty, Time’s Square, 9/11 Memoral etc as well of the Metropolitan.  It sounds like the bus from the park is a good overview, but won’t replace extra time at some attractions.  How long would you allow if staying at a motel for Manhattan & midtown areas.  Thanks!
