1. Go check out your room. Look in all the empty closets, look in the bathroom, sit on the bed, sit on the couch, go out on the verandah if you have one and look around, pick up the phone to see if it works, check out your excursion tickets which might be in your room in an envelope, check out the wavephone things, turn on the TV and flip thru the channels, go to the bathroom, 'claim' a side of the bed, 'claim' the set of drawers you want for your clothes.
This will take about 10 minutes.
2. Go eat.
3. Walk around the ship exploring.
4. Go to room to see if your luggage has shown up yet. If it has, unpack.
5. Go up on deck and have a drink of the day and see what is on the big screen mid-ship.
6. Read the Navigator to see what is going on that night and what movies and shows will be shown when/where during your cruise.
7. Stare over the side of the ship at the dock workers and see if you can find your luggage among the thousands of bags being loaded.
