Three Luxury Cruise Lines Face Off on the High Seas (onemileatatime.com)

A traveler who sailed each of the three lines finds Ritz-Carlton Yacht Collection the best value with the most interesting itineraries, Four Seasons Yachts the most family-friendly with the best pool and spa, and Orient Express Sailing Yachts the most luxurious but at a higher cost. Daily rates vary widely, from about $1,000–1,500 per person on Ritz-Carlton to $3,000–5,000 per cabin on Four Seasons.
