1. European River Cruise
Cruise the rivers of Europe for a new way to see different places, all from a luxury ship. Since most big cities in Europe were built along waterways, there's a lot of history to experience on these river cruises. For example, a Danube River cruise goes through up to 10 countries. Cruise through old-world cultures, beautiful countryside, and bustling cities that shaped all of Europe.

Other river cruises can take you through a single country such as France or Portugal. Although there may be additional fees for excursions, museums and such, everything else is typically included. Like most cruises, look for last-minute booking opportunities for the best value.
