One of the biggest problems I had with smoking was traveling and finding a place to have a cigarette. We'll be cruising in a couple of months and I'm told on the Cruise Critic Board that E-Cigs are classified just the same as regular tobacco so you have to be in the 'smoking section' to use them. Some say that they've done it anyway and been 'discreet' and not been bothered. Others say it's just so new and people freak out and carry on (ALL non-smokers do if you ask me .... some are SOOO over the top!! LOL!) so it's just easier to ask the person not to do it. I wondered about doing it in the bathroom on a plane??? Sure wouldn't want to set off the alarm and get kicked off!! LOL!!
