Can you suggest a few tour operators that organize adventure trips for solo travelers?

Cyclists on Footloose/TrekAmerica's new Southwest Mountain Bike Tour (800/221-0596;; June 16-27; $1,199, including camping gear and admission to all national parks) will traverse backcountry trails in Moab, the Grand Canyon, and Zion National Park, camping along the way. • The roommate-matching program at Singles Travel International (877/765-6874; allows guests to avoid a (low) single supplement of $500. On its shipwreck diving trip to Chuuk, Micronesia (April 24-May 3; $2,775, including airfare from Houston and accommodations), divers can explore more than 50 coral-covered vessels that have been buried in Truk Lagoon since World War II. • Singles in Paradise (800/954-5453; organizes trips to Greece, Belize, and Russia, but athletic types will want to sign up for "Multisport Maui" (July 17-24; $1,079, including airfare from the West Coast and seven nights' accommodation). Excursions—which cost anywhere from $45 to $245 extra—range from the low-key (guided hikes to the island's tropical interior) to the adrenaline-pumping (paragliding off Haleakala volcano).

My husband and I are planning an Alaskan cruise—which ones do you recommend?

This spring, Princess Cruises launches its 1,337-room sister vessels, Diamond and Sapphire Princess—the largest cruise ships ever to sail to Alaska. A seven-day round-trip voyage from Seattle (800/774-6237;; doubles from $1,798) offers glacier viewing and Klondike excursions—along with innumerable onboard activities (each ship has four pools, a casino, a nightclub, a putting course, and even a wedding chapel). Holland America's Oosterdam also begins plying Alaskan waters this season on a seven-day round-trip cruise from Seattle (877/724-5425;; doubles from $1,798). The first of Holland's ultrasleek Vista Class ships in the Northwest, the Oosterdam has verandas on two-thirds of its 924 cabins. Silversea's Silver Shadow is adding Alaskan routes in June, the best of which is a 10-day trip from Anchorage to Vancouver that stops in bygone mining towns and historic ports (800/722-9955;; doubles from $8,000). With a Mandara Spa, Frette linens, Bulgari toiletries, and teak balconies, the 192-room ship ensures that passengers will be afloat in luxury.

I'm booking a trip through a travel agency located outside the United States. Are there any travel insurance companies that provide coverage for vacations purchased overseas?

Most major domestic travel insurance companies offer both trip cancellation policies and emergency medical care coverage for trips purchased abroad. If you want additional perks like last-minute flight changes, cash transfers, and restaurant reservations, sign up for Travel Guard International's "cruise, tour, and travel" plan (800/826-7791; "five-hour trip delay" benefit in Travelex Insurance Services' plans (800/228-9792; covers meals and lodging if you're stranded en route for five hours or more. CSA Travel Protection (800/348-9505; rewards tardy planning with its "impulse travel discount." Booking a trip and buying coverage within just 15 days of departure earns travelers a 15 percent saving on their policy.
