To me, the biggest change in cruising has been the availability of balconies. With the advent of all balcony cruise ships in 2001 with Seven Seas Mariner, Radisson showed that you could pay for the cheapest cabin instead of the most expensive suite and still get a spacious balcony. Since then, ships such as Sovereign of the Seas and Celebrity Century have been modified to add balconies. A case in point was a CruiseMates cruise that was planned for last year (or year before) on the Century. For me to get a balcony on Century, I would have had to pay more than I would have had to pay to sail Radisson or SilverSea in the Caribbean.
