Do we check-in by booking number or last name? We are surprising my dad on the boat and don't want anyone to give away the surprise when he checks in and sees that there are a bunch of people with the same (uncommon) last name!
And how do we make calls from stateroom to stateroom? My mom is going to call us from their room to let us know they're onboard so we can come to their room for the surprise.
Your replies are much appreciated!!! 8)
