Add second adult and upgrade after final payment date - reprice ?

[DensolandMouthy]

I have an inside booked for one person on the Epic transatlantic in April. If the price drops after final payment and I add on a second adult at that time and we upgrade to a club suite, do NCL reprice the cruise at that dates lower going rate ?

They may charge you a penalty to cancel what you have and charge the going rate for the upgrade if you got a solo discount.

If you paid for double occupancy for your current cabin, you can possibly add them to your current booking by paying taxes etc. You might also be able to pay to upgrade, if the cost is more than what you paid - those decisions are made on an individual basis and are not guaranteed.
