Carnival has given a decent (in my opinion) compensation to the passengers on board right now. Their itinerary changed again since this posting, they will only be able to go to Costa Maya and Cozumel, and the comps increased to $200.00 OBC and 50% off a future cruise plus a few other extras. I feel bad for the next sailing as theirs will be cut short by a day since this sailing is taking an extra day to return. Mine is the one after that, so fingers crossed that they figure out what the issue is and have it taken care of by the 29th. I will not worry about it until June 28th at midnight LOL And even then, i probably won't worry too much coz any cruise is better than no cruise!!
