We have recently returned from an 18 day (BtoB) cruise on Vista. The ship is beautiful but we found it not quite as excellent as our many other Oceania cruises so I started researching reviews on Regent Seven Seas, Seabourn and SilverSea. Many of the recent reviews of all these lines complain that "it's not what it used to be". So it's not just Oceania that is receiving the poor reviews. All of the so called luxury lines are seeing their star ratings going down. It could very well be that the lines are having a more difficult time attracting staff.
We will continue to sail with O. We look for the small ships without the glitz, water parks and party atmosphere.
