RichC....It is the "WOW" factor.....Cruiselines seem to be trying anything that might attract whole new generations of cruisers!!! There is no limit to the ideas floating around between the Designers, the Engineers, The Shipyards, the Cruiselines!! Todays new cruisers are looking for newer and different activities from previous generations!! Cruises were once tremendous sources of relaxation and phenomenal ways to distress!!! The larger and newer ships emphasize activity and seem less personal!! Nowadays the ships libraries,reading rooms and card/game rooms are used far less than in the past!! Uniqueness is becoming the new drawing card!!! Welcome to cruising in the 21st Century!!
