It doesn't sound romantic, but a freighter cruise can be fun and cheap. The fares for freighter travel can be less than $100 a day per couple. Considering that this includes all meals and other services, a freighter ship can be a real bargain.

Most freighters carry no more than a dozen passengers. Staterooms are large, similar to those on the most expensive cruise ships. Many freighters have a swimming pool, gym and other recreational facilities. The ship's agent is the first person to board the ship once it docks. They will advise you on shore-based excursion operators.

Freighter travel is leisurely, and routes take up to a month or two to traverse. Delays are part of the experience. The ship waits for cargo, not passengers.
