Aero maybe give it some thought before canceling and loosing any money.... Yes there is Splendor, Triumph, Dream, Legend and Elation. It's becoming the new norm for Carnival. I understand cruisers being worried if their cruise ends up being a poop cruise or if their cruise ends up being cancelled due to previous problems.
Dream, Legend and Elation came too soon after Triumph... Issues happen on all cruiselines but poop in a bag cruises are (so far) only on Carnival.
You like the Carnival product I would just go with no worries. Maybe future cruise it may be a good idea to try something new at that point. As a Royal cruiser I wanted to try something new and cruised on Breeze. The Carnival product is not for us. The entertainment on a brand new ship is terrible.
I'm looking forward to NCL Breakaway later this year or early next. It's good to switch it up sometimes....
