@FBM,
This is an interesting subject, because the group I travel with most often are drinkers, and you can find most of us at the bar quite often during cruises. Even the travel company owner will usually have a glass of wine in her hand - most of the time. We all drink other stuff too! We travel to Cuba often, and we have their best beer called Bucanero, and we'll most often have wine with dinner. During the day or evenings, we have mojitos, pina coladas, martinis, and other drinks.
As a matter of fact, I'm leaving on the 27th of this month (in 3 days) on my way to San Juan to meet up with our regular travel group to spend a couple of days in San Juan before we go on a wine cruise on Oceania's Insignia, one of our favorite ships with 650 passengers. Our port stops will be at St Barts, Antigua, Saint Lucia, Barbados, and Grenada before we return to San Juan. We're returning home on December 7th, then on December 10th, I'm off again to Spain and Portugal with a retired professor I met on a cruise last year on the Rhine and Mosel.
I don't drink too much when I'm at home, but I do have a bar filled with liquor, and a cooler full of wines.
I read the book, "I'll Cry Tomorrow" written by Lillian Roth, the actress-singer who was an alcoholic, but she did recover after hitting bottom. She made millions, and ended up penniless.
