I see, thank you, truly appreciate your input.
Would the easiest way to go about this be to have the no-show still complete the check in, and then have the attending party member report the no-show at the port on the departure date?
I won't be charged more if I sail then, even without the other person there? I just want to avoid any surprise charges-- we're splitting costs and I don't have as much of a budget as my hospital-working-friend, haha.
