For many travelers, cruising is synonymous with romance and the nostalgia of old-fashioned seafaring. Cruises are an easy way to enjoy full itineraries and special excursions without all the landside luggage schlepping. Yet some people still resist, thinking the tradeoff of a packaged voyage could never beat the freedom to choose one’s own adventures. But what if a cruise is the best way to a hard-to-reach destination, or even several of them, in a single vacation? Maybe it’s time to consider one of these out of the ordinary cruise ideas to see what special locales await in distant harbors.
