Count on 3 more.  Myself (K9DLP), my wife (K9SCP), and my daughter. I upgraded to an ocean view ($7.00 more per person than the reserved inside cabins).  Comes with a King size bed, a sofa couch, and a 3 foot by 4 foot window.  I mentioned the AMSAT code and they said AMSAT will get credit for our 3 reservations.
