Am trying to think of what could have improved this cruise and am coming up blank. We have cruised a lot and were last on Reflection in April. Was so warm that the pools were totally useable. Luminae was terrific, loved our butler & cabin attendant, fun crowd, silent discos. We toured on our own mostly but did the tour to Cinque Terre with ship & it was wonderful. Hard to pick a favorite port but loved overnighting in Barcelona. I love overnighting And feel every cruise would be improved by having more of them.We disembarked in Ibiza & spend a few days there before going to Madrid. I think the next time they do this itinerary they will visit Mallorca instead. One negative was that the 2019 cruise for this ship(same time of year) came out on the last sea day so we missed the opportunity to book that on the ship. Thank you Celebrity!!!
