The fun doesn't stop just because the sun has set. That's the idea behind Crystal Cruises' itineraries that will pass by some cities during the day and overnight in key ports, where passengers might take in local entertainment or dine in a top restaurant.
"Crystal’s itineraries will also intentionally deviate from traditional river cruise routes to avoid congestion of other vessels in port," a company statement said about its itineraries, which will start in March 2017.
Crystal also plans to add more active excursions for passengers who want to explore cities by bicycle or Segway. Passengers also will have access to a tender to seek out more private destinations, an unusual feature for a river ship.
