There are a lot of cruises out there. Some are multi-week trips that can span continents, while others can be as short as one or two days. But not all cruises are created equal. This is particularly true of those on the shorter end of the cruise spectrum, where so-called “getaway” voyages can sometimes equal the cost of a full weeklong voyage.

Here are four cruise itineraries that may not be worth your time or money ... and five alternatives that definitely are.
