This will be my first cruise on Royal. I have a question about the internet package. We just found out that our daughter is going to have her commissioning ceremony for a two year missionary position while we are on our cruise in March (Our last day at sea). We did not know when we booked the cruise when this would happen. The event will be live streamed for those that cannot go. Can I purchase internet just for 1 day? I do not plan on using it for anything other that this. If I have to purchase for the entire cruise that is fine and of course I will do that. I am assuming it can be used from my laptop, but not another device unless I pay for the second device. Thank you for your assistance.
