Yes @Fouremco, the exchange rates always get us. We did our first cruise with RCL and did not purchase the DBP until we ordered our first drink, quickly did the math and ended up purchasing on the ship as it was still a savings - although not as good a savings as purchasing in advance. Of course, it depends on what you enjoy for beverages, but we do find it a significant savings....and no bill at the end of the cruise is also nice!
