Inside Passage, Alaska
Maridav/ShutterstockYes, you can see the ruggedly beautiful coastline of Alaska's Inside Passage—complete with whale (and eagle and bear) sightings, and glacier calvings, and kayak tours—without giving up creature comforts. After a day in a National Park, what about a "Caviar on Ice" deck party, anyone? Now, that's how to see the Last Frontier. Not only is this one of the best cruises in this part of the world, this is also a new experience, as the ship has just moved to Alaska for the first season there this month.

Leonid Andronov/ShutterstockYou can still cruise from America to the United Kingdom on one of the last great ocean liners, which makes regular sailings across the Atlantic Ocean. Best of all, the experience has many nods to the glamorous crossings of the past, from afternoon tea with white-gloved service to formal nights with dancing to an orchestra. On deck, you can still watch the horizon and sip bouillon in a teak lounge chair. In addition, the ship was recently refreshed and also has solo cabins for individual travelers. These are the best vacations everyone should take by themselves.

Say you love the salted caramel parfait dessert one night, and you may just find handmade salted caramels in your cabin the next afternoon.

Just remember: This cruise will eventually take you to a beach in Rio, so consider saving that dinner for later in the cruise. Find out 28 secrets the cruise lines won't tell you.

Leonid Andronov/ShutterstockIt may be a point of discussion that the line claims this 600-passenger ship is the most luxurious ship in the world, but she sure is gorgeous. Picture beautiful suites with every bit of molding and paneling that you would expect in a private estate, as well as gorgeous marble bathrooms you'll wish you could take home with you.

Mekong River, Cambodia, and Vietnam
Dmitry Rukhlenko/ShutterstockSure, you can't do this trip without schlepping to the other side of the world but, trust us, it's worth the jet lag. Rolling down the Mekong River means a chance to see Buddhist monasteries, explore temples, take cooking classes in how to make green papaya salad and chicken curry, and shop for gorgeous raw silk scarves. Onboard, even though the 68-passenger vessel is small, there's a sweet little pool to relax in after long days of sightseeing, and cocktails that use local ingredients, such as kaffir lime and Cambodian espresso.
Ship: Scenic Spirit
Where it Goes: Travel from Siem Reap in Cambodia to Ho Chi Minh in Vietnam.
