That has been one of my assigned tasks whether we cruise alone or in a group. I check prices (we have only done 3 different lines) one or two times a week for a price break and make the call directly. It has been a very simple matter (esp with RCI) to get it updated while speaking with a rep on the phone. Our Last Princess, we were 6 in our group and it added up to quite a bit over time prior to the cruise. Great feeling huh ? !!
