The Bahamas are ready-made for exploration. Just ask Christopher Columbus, he bumped against these limestone landscapes in 1492 and changed the course of history,But adventure didn’t end,wily go-getters have converged and caroused on the country’s 700 islands and 2400 cays for centuries.But every adventure has irritations, and here indifferent service, high prices and hungry no-see-ums take the lead.Nassau and Paradise Island are the prime troublemakers. But if casinos, Aquaventure and duty-free shopping don’t top your to-do list, consider dropping off the grid for a bit in the Out Islands. Prices remain high but there’s more bang for your Bahamian buck, with friendlier service, fewer crowds and, well, the pesky no-see-ums haven’t gotten the memo.
