The party’s over. Or is it? Keep your prom or graduation celebration going through the wee hours of the morning with a Moonlight Cruise. Set sail after midnight and dance to the beats of a local DJ. Play casino games. Enjoy delicious hors d’oeuvres and all the soda you can swallow—not to mention mind-blowing views of the San Francisco Bay. With Berkeley in your wake, you can snap endless photos of you and your friends on the open sky decks and post them to all your favorite sites. So when the first party ends, have a second one—and make it unforgettable, on a Hornblower yacht. Total bonus: It’s surprisingly affordable.
