My husband and I were on the earlier South America circumnavigation (we were home by December 3?). As far as either of us recall, we didn't have an "open bar." Nonetheless, I doubt, with the various receptions and special parties for the circumnavigators, that we ever had the need to buy a mixed drink at the any of the bars. As I recall, a friend of ours did sign for beers (at all hours of the day). That's just our recollection.
