The 50,000-ton, 940-guest sister ships Crystal Harmony and Crystal Symphony, are two of the most spacious and luxurious vessels cruising the world. Their unique size in the luxury market allows for smooth sailing and a wide range of innovative facilities, generous amenities and elegant accommodations. The Six-Star rated liners feature grand lounges, a lavish spa outfitted in accordance with the principles of Feng Shui, extensive exercise facilities, complimentary golf, yoga and Pilates instruction, the only Caesars Palace at Sea Casino afloat, and the innovative Computer University@Sea, offering 24-hour e-mail and internet access, as well as hands-on instruction, expansive decks, two pools, award-winning cuisine and entertainment, and exquisitely-appointed staterooms, more than half of which offer private verandahs. The 68,000-ton, 1,080-guest Crystal Serenity will feature an even greater space-per-guest ratio than her sister ships. Plans include expanded areas for spa services and other athletic, cultural and intellectual pursuits. Within a range of luxury accommodations, the line will increase its number of penthouses and enlarge its deluxe staterooms with verandahs. Approximately 85 per cent of its all outside staterooms and suites will offer private verandahs. The luxury liners are operated by Crystal Cruises, winner of the travel industry's most distinguished hospitality awards and guidebook ratings. Its most recent honors include an unprecedented seventh consecutive "world's best" large-ship cruise line award from Travel + Leisure magazine, and a number one ranking for cuisine from the same publication.
