Love the space, the spa, and the larger suites with markedly upgraded bathrooms. Hate the cramped little workout room. That's the consensus among passengers on the sixth voyage of the 382-passenger Silver Shadow, the newest deluxe cruise ship. In fact, the Silversea cruise line faced a challenge—topping its first two vessels (Silver Cloud and Silver Wind), which benchmarked luxury cruising in the mid-'90s. The solution: Add 100 feet in length and 10 feet in width, expand interior space by half, but increase the number of passengers by just 86. Indeed, Silver Shadow is the roomiest cruise ship afloat. She sails the South Pacific through April, then the Indian Ocean, then European waters in the summer. $850 per person per diem. 800-774-9996; www.silversea.com.
