Choosing to cruise on a vast ocean or a mighty river is a common dilemma as both cruising styles are so popular on the international travel scene.
An ocean cruise can resemble a holiday at a land based resort. All manner of activities fill the day with an exciting range of restaurants and entertainment by night, especially on the new generation of mega ships that carry 2000-plus passengers.
By contrast, australiancruisingnews.com finds that river ships, with about 150 guests on board, are all about regional immersion with a new port to explore every day. Time spent aboard a river ship is focussed on relaxation after another busy day exploring on foot or by bike.
While river ships anchor in the heart of a city or in an interesting small town, larger ocean-going ships often need to berth in deep water ports that are a coach ride away from the main attractions.
Distances covered overnight on a river cruise are tiny compared to the rapid rate of knots of an ocean liner that may spend days at sea cruising from one continent to another.
Destination also plays a decision-making role as river cruises usually sail through a country while ocean cruises hug a coastline or traverse vast oceans.
In the long run, those torn between a river or an ocean cruise need to decide what they really want from their holiday on the water.
