Adding CC nr to online check in???

[skrapngal]

So our cruise is 35 days away WOOOOHOOOOOOOO.

 

We have checked in online and had put in "cash account" but would now like to go put a credit card number. But the "expenses" portion of the check in is greyed out (it cannot be selected).

 

I know I can go to guest services once onboard, but I was hoping to avoid the line and do it now.

 

Any thoughts on why it won't let me do it now?

Just do it at check in. It will add 15 seconds to the process
