The Kennedy Space Center is a must. Plan for an entire day; check the bus schedule to get out to the Saturn V assembly area after the Imax thing. Rent a car no matter where you fly into Florida and stay in Cocoa Beach at a good hotel on the beach, just not Orlando. Believe me, hotels will cost the same, be way nicer, and you won’t have to think America is one long line of huge African American women waiting in line at 8:00am juggling a 20 plate of free bagels in the hotel lobby.
Then skip New York and fly into Reno. Go skiing in Tahoe, leave some state tax dollars downtown after a $7 steak and eggs, and see a show or 2.
