Back yesterday from a Western on Celebrity. First and most importantly, my kids (boys- 22 and 27) did NO damage to our house in our absence and all of the pets are alive. Now on to vaping. I vaped anywhere and everywhere I wanted except in the MDR, Buffet, and inside the shops. I got a few looks- mostly curiousity and a few questions. I think people did not care and it did not take them but a quick glance to realize that it was not a cigarette. I am really pleased. Celebrity has a strict smoking policy and I was able to vape in our stateroom and on the balcony with no problem. There actually did not seem to be very many smokers on the ship. Even though the smoking sections were frequently occupied, they are relatively small. I think most smokers probably booked on more smoking friendly cruise lines and that is okay with me.
