Drive time from Miami is almost exactly the same as to Key West. But the similarities stop there. Captiva does not cater to inebriated college kids staggering down its main tourist drag. Captiva doesn't even have a tourist drag. The closest thing to Duval Street you'll find on this barrier island west of Fort Myers and north of Sanibel is a dusty little path called Andy Rosse Lane, which dead-ends at the beach and the venerable Mucky Duck pub and grill. A cluster of restaurants and shops dot the lane, but there's nothing approaching a Key West saloon. That's not why people vacation here, or build waterfront mansions here. Captiva is captivating because it is quiet, relaxed, civilized, and hemmed by a wide, inviting beach. Another attraction: The shoreline faces west, across the Gulf of Mexico, which means every day you can saunter down to water's edge and watch the sun set. The light shows are often spectacular. Aside from the South Seas Resort (941-481-3636), a sprawling complex occupying the north end of the island, there are only a small number of hostelries: 'Tween Waters Inn (941-472-5161), Jensen's on the Gulf (941-472-4684), Jensen's Twin Palm Marina (941-472-5800), and the Captiva Island Inn (941-395-0882). Demand is high, supply is limited, and therefore rates can be pricey, though summertime is reasonable. But you're not staying for a month; you're just popping over for a quick getaway, a weekend retreat to restore your soul. Captiva is worth it.
