When I fist read the title of your thread, my mind jumped to: "WHAT?! CELEBRITY PURCHASED VIRGIN"?! 🤣 😂
We had a few cruises under our belt when we decided we wanted a full 2 week cruise. The best itinerary at the time was 2 weeks on Eclipse (an S-class ship) so we booked Aqua class and had such a wonderful cruise, we booked the same cabin on the same ship with the same itinerary a year later! The Celebrity cruise was superior to the other cruise lines that we had previously sailed with - the difference was demonstrable! We have never regretted it.
Since then, we've only sailed Celebrity (always in Aqua class) and have no desire to sail with anyone else! The service, the food, the entertainment (well, sometimes it's 'meh' but never-the-less, we like it), the no smoking policy, and especially the positive attitudes of the crew have kept us returning since 2014.
We will sail in Edge class, and in a suite, for the first time next week! I expect we will feel spoiled yet again!
