Better to book single occupancy or double with only one person sailing?

Son is planning a trip to Japan but is finding it hard to find someone to accompany him (expensive).  He hay have a cousin join him?  Is there a draw back to booking the room as double occupancy vrs solo and then just have his cousin now show if he cant make it?

There are taxes, fees, and port expenses in addition to the room cost. If you book double occupancy, you would need the name of the second passenger and would need to pay these fees.

Not all cabins have a single supplement. If he travels as a single, he will get double cruise credits

He should book as a single- Princess occasionally has some single supplements that are less that double occupancy costs depending on the voyage.  Plus with single occupancy he will only pay one set of taxes, fees and port expenses. And since insurance is based on cost of fare, it will be less if booked as a single.

 

If he finds someone who wants to sail with him it’s easy to add the second person to the booking.
