Here is the short version. American Cruise Lines is one of the easiest lines in the United States to sail alone, and one of the most expensive. Every ship in the fleet has single staterooms priced for one. The ships carry 90 to 180 guests, nobody dresses up, and a crew of Americans learns your name by the second morning. If the fare fits, it is close to a solo traveler's ideal. If it does not, no amount of friendliness will change the math.
Small ships, one country
The line sails only in the United States, on the Mississippi and its tributaries, the Columbia and Snake, the East Coast from Maine to Florida, Puget Sound, the Great Lakes and Alaska's Inside Passage. Its ships fall into a few families. The modern American Riverboats such as American Melody and American Serenade carry 180 guests and have a glass atrium that rises through the ship. The Coastal Cats, including American Eagle, are 100-guest catamarans that reach small harbors on the coasts. The Patriot-class ships such as American Patriot carry 130. There are also four traditional paddlewheelers, with American Heritage among them, and a few older coastal ships of 90 to 170 guests.
Whatever the hull, the pattern is the same. One restaurant, one open seating at dinner, a lounge with a bar, an evening of live music or a talk from the onboard expert, and a port nearly every day. There is no casino and no production show.
The single staterooms
American Cruise Lines builds single-occupancy staterooms into every ship and describes them as the largest in the industry. Many have a private balcony, and the rest have large water-view windows. They are priced for one guest, which means no supplement to calculate. The number per ship varies, from a couple on the smallest coastal ships to more than a dozen on the bigger paddlewheelers, and they are among the first categories to sell out. If you want one on a fall foliage cruise in New England or a summer Alaska departure, plan on booking many months ahead.
If the singles are gone and you still want to go, the line's policy is clear: a solo guest in a double stateroom pays 150 percent of the double-occupancy rate. On a cruise where the per-person fare starts around $5,000, that is a $2,500 surcharge. It is not the worst in the industry, but it is not a bargain, and the line does not advertise reduced-supplement sales the way some European river lines do.
What is included
Part of what makes the fare easier to accept is how much it covers. Meals, wine, beer and cocktails, the nightly cocktail hour, gratuities, port charges, a hotel night before you board and at least one shore excursion in every port are all in the price. For a solo traveler that matters more than it might for a couple. You are not quietly paying for a second cocktail or tipping at the end of the week from a single wallet. Premium excursions cost extra.
Meeting people
The line does not run formal solo meetups, and it is honest about that. What it has instead is a ship small enough that meetups happen on their own. The cocktail hour before dinner is where the whole ship ends up, and it is the natural place to find a table for the evening. Dinner is open seating, so you can sit with new people each night or settle in with a group you like. The onboard expert's talks and the included walking tours, museum visits and nature outings put everyone in the same small groups day after day. By midweek a solo guest knows most of the ship.
The crowd is mostly American, mostly retired, and interested in the place they are visiting. Conversation runs to Civil War history, Lewis and Clark, lighthouses and glaciers more than to nightlife. If that sounds like your kind of week, you will fit in without effort.
Itineraries that suit solos
The line's own blog points solo travelers to Alaska, the Columbia and Snake rivers, New England in the fall, and the Lower Mississippi over the holidays. A good first pick is a week on the Lower Mississippi between New Orleans and Memphis, where the ports are easy and the ship's expert does most of the work. The Columbia and Snake trip from Portland is scenic and relaxed. Alaska on a 100-guest Coastal Cat gets closer to the glaciers than a big ship can, but it is the priciest of the lot.
Who it suits and who should pass
American Cruise Lines suits a solo traveler who wants a domestic trip, a cabin of their own, no flights overseas and a quiet, intelligent atmosphere. It is a strong choice for older travelers and for anyone who finds big ships overwhelming.
It is the wrong pick if budget matters most, if you want a lively bar scene past 10 p.m., or if you want foreign ports. Note too that medical care on board is limited to a trained first responder, so anyone with a condition that needs a doctor close by should think carefully. For everyone else, book the single stateroom early and let the river set the pace.
