4. New York City, NY New York City in the summer? Why not? A lot of locals actually leave NYC during holiday weekends in the summer, which means you can get into restaurants and avoid lines at kid-friendly museums. Hotels might not be cheap, but you can check out home-stay options through websites like AirBnB and VRBO to find furnished apartments that are family and budget-friendly. Plus there are tons of parks all over the city to check out, you can visit Coney Island, and the Macy’s Fourth of July fireworks show is unlike any other display in the country.
