Our third person can’t go with us now. I’m scared if I call to cancel the third person, Carnival will try to make us move to free up that triple occupancy room. There are no more Havana Cabana rooms available on my sailing. Plus we’re not sure if another friend might come instead. To complicate matters I booked an ES rate. It’s not the money that I’m looking to get back, I just don’t know the procedure if only 2/3 people show up to board. And if we do find a third person, will they let us cancel and rebook that new person (at the higher rate it will be)? We are still outside of final payments. Advice?
