Being from NY, I can't picture being on a plane that long to experience Hawaii, quite frankly.

As for the East Coast, it's very nice to see Mystic, CT, Newport, RI, Boston and Cape Cod, MA, and there are tons of pretty towns in VT and NH. We went to NH with my daughter to visit a college and fell in love with the town. It had a lovely downtown area with craft stores and neat cafes and restaurants, and it was all very walkable.
