My boyfriend is a smoker and he does not go long periods of time without smoking. He smokes before he goes in to work at 7, he "steps out" for a cigarette around 830, takes his regular break around 1015 for a cigarette, he chain smokes on his hour lunch 12-1, "steps out" again around 2, takes his second regular break around 315, and then smokes a few on the way home at 4.
So that's at least 5 smoke breaks in a 9 hour park day for us. 5 times going in and out of security. Possibly all the way back to our resort or car if they ban them in the parks altogether. That is a huge blow for smokers. It will be very inconvenient for our family, and I guarantee for many others. Especially European guests.
