We just took our first Regent cruise in November after being loyal Crystal cruisers (no more). We have also sailed Silversea (which we like a lot), Seaabourn and the Paul Gauguin. We have 15 cruises on Oceania (never again) and a few on Celebrity. We board Regent again on Jan 5 and we have several more booked. We now only book luxury lines.
We were wowed. Splendor was gorgeous. Food, service and accommodations were superb. Entertainment and lecturers really surprised me (I was not sure Regent could equal Crystal in that area but it did). I am not crazy about included excursions so will book private in some ports as I have always done.
