Does smooth sailing and smaller group gatherings with a more intimate feeling appeal to you?
Or, do you prefer the hustle bustle of a huge group and long walks to get all over a ship as well as on and off?
Do you prefer all-inclusive sailings with soft drinks, wine, beer and perhaps other alcohol, including shore excursions? Perhaps you like paying extra for all of that?
In a nutshell, I believe that River Cruising is a most enjoyable way to travel and gives you greater value because of their all-inclusive deals.
