August Domestic: New York City

Double check that your hotel is well air-conditioned—New York City summers can be stifling. But they’re a great excuse to hit trendy juice bars (we love Joe and the Juice in Soho) and take advantage of summer events, like outdoor New York Philharmonic concerts and Shakespeare in the Park, which are totally free to attend. Stay in the last week of the month for the deepest discounts on accommodations.
