I just went on cruise to the Galapagos Islands in Sept. Small ship, just 16 passengers. 11 crew, and 1 naturalist. We vaped everywhere and never had one complaint. I do feel the reason is that everyone asked about it and was interested in how it worked, either for themselves or their family and friends who smoked. At one point, the naturalist asked us to give a spiel on it after his briefing since so many people wanted to know more. Everyone stayed to listen. Communication is the key to acceptance.
By the end of the trip, we converted 4 smokers (all of the smokers on board not including my husband on I). All the non-smokers wanted business cards for family and friends...and several emailed us later with success stories for converting them...and thanked us profusely for giving them a heads up about ecigs.
The best story tho, is about the naturalist...he is now a rep in South America and is selling them. Says the interest has been incredible...and business is booming. He has not had a real cigarette since the cruise (we gave him enough from our stash to hold him til he ordered.)
I know this situation was unique because of the small number of people on the ship. But hey, its a start...and its always nice to hear good news, right?
