When Royal Caribbean's Ovation of the Seas came Down Under for the first time, people wondered if anyone would bother getting off the ship in port. Why? Because it could take about a week to try out all the various entertainment options and activities onboard. But you don't need to sail on a 5,000-passenger ship to get the most from your days at sea. Any ship will do if you're content to spend your time passed out on a sun lounger.
Those who do want a mix of action and relaxation should know that it's key to pick the right ship -- and the right itinerary. Australia is a long way from pretty much everywhere else and therefore an ideal jumping-off point for fans of consecutive sea days. It takes two to three days to get to the South Pacific or New Zealand, while repositioning cruises can sail for a week without a port of call.
Now that you know what to look for, here's our selection of the best ships for days at sea. We chose our favourites based on their variety of onboard attractions -- both indoors and out -- to keep cruisers of all ages entertained.
