Paying for others photo packages on my card?

[jpeka65844]

Will this be a problem at all? We're getting the 50% off Friends and Family deal for 2 staterooms' photo packages. We can't add it until we're onboard and to make it easy, I'd just like to take care of it on my card; rather than truck everyone else to Shutters.

Does anyone know if I can pay for others stateroom photo packages on my card?
