We are going on a cruise next march. I booked a balcony for the two of us, , unfortunely she can`t come. I am going alone, i am willing to pay
double for the balcony.
Do I have have to tell them That I am going alone . Can I tell them
when boarding the ship that my better half is not coming.
You can do it either way; if you tell them now, they'll refund the taxes for the second person now. If you wait until you check in at the pier, they'll refund your taxes then.
Sucks you can't find someone else to go with you because, as ruth stated, they would only have to pay the taxes (and of course gratuities).
Perhaps you might want to look for a roommate - plenty on here are looking.
