And for places to stay in Key West, there's a wide range of top options, from cool boutique hotels in heritage buildings fringed by tropical gardens to big establishments like Opal Key Resort & Marina or the Hyatt Centric Key West Resort and Spa. By night, tuck into freshly caught fish at Key West's many seafood spots, before hitting the bars and dancefloors of Duval Street, the heart of the city's nightlife. During the days, you can enjoy the warm Gulf waters with activities like paddleboarding, kayaking and snorkeling, or get a hit of culture with a visit to the historic former home of Ernest Hemingway to meet the six-toed cats.

Mixing together relaxed tropical vibes, historic ambiance and a party atmosphere, Key West is a particularly unique bachelor party destination. As a bonus, San Diego is a good year-round choice for a bachelor party thanks to its mild climate that rarely gets particularly hot or cold. Alternatively, there's also the town of La Jolla, a bit further north, known for its stunning coastline, surf and museums. Ocean Beach is also a great place to hang out and take in the bohemian vibe, perhaps while stopping by one of the various breweries or taco stands. During daylight hours, take to the sea: The funky town of Ocean Beach is home to numerous surf schools (after all, this part of SoCal is a serious surfing hotspot).

Consider a bar crawl through that part of the city – there's a range of clubs in the area, if the mood strikes. This California city boasts a hefty range of festivity options, thanks to its long, beach-lined coast, and lively neighborhoods like the historic Gaslamp Quarter, a 16-block downtown area packed with bars and restaurants. If the groom-to-be isn't inclined toward the brash debauchery of places like Vegas and Miami, consider San Diego.
