According to the Disney Mom’s Blog on the Disney web site, e cigarettes are not under any separate policy, but fall under the smoking policy which is: “Walt Disney World restaurants, shops, theme parks and Resort hotels are smoke-free environments—except for designated smoking areas. The printed theme park Guidemaps available at the park Main Entrance show the designated smoking areas.
All Disney Resort hotels at Walt Disney World Resort are smoke-free environments. Smoking is not permitted in hotel rooms. Smoking is allowed in the designated outdoor smoking locations of each Disney Resort hotel. Guests can request location information upon check-in.”
