Which Should You Visit?
Both islands promise golf cart transportation and sunset rituals, but they deliver fundamentally different experiences. Isla Mujeres sits eight miles off Cancún's coast, where peso pricing meets turquoise Caribbean waters and Maya-influenced culture. The island measures just five miles long, with Playa Norte anchoring the social scene and downtown centering on simple seafood and cerveza. Key West occupies the southernmost tip of the Florida Keys, where American infrastructure supports a more developed tourism machine. Mallory Square's nightly sunset celebration draws hundreds, while Duval Street offers polished bars and restaurants at mainland US prices. The choice hinges on whether you prioritize Isla Mujeres' affordability and authentic Mexican island atmosphere or Key West's established amenities and English-speaking ease. Both promise barefoot relaxation, but Isla Mujeres skews simpler and cheaper, while Key West delivers more activities and dining sophistication.
