Back in December I booked the Seaside for this coming May.  I talked a friend into booking their own cabin.   Approaching final payment my friend noticed his fare went up ~$82 since we booked in December.  Checking my booking I had the same ~$82 rate increase.  The two bookings are separate and not linked.     I have the original booking confirmation email from December and it clearly shows the rate I booked under.  Now the cruise invoice is showing a total that is ~$82 more.
