On May 1, Disney parks in Florida and California will become smoke-free, the company announced on Thursday. Visitors who want to smoke at its theme park properties, including Walt Disney World, the ESPN Wide World of Sports Complex and two water parks in Orlando, as well as Disneyland and the Downtown Disney District in Anaheim, Calif., will have to do so at designated locations outside the security area, according to a post on the Disney Parks blog. “As we expand our offerings, we continue to take steps to enhance the guest experience and make it more enjoyable for everyone who visits,” Liz Jaeger, a Disney spokeswoman, said. It will be up to Disney employees to enforce the ban, she said. “Employees will ask anyone caught smoking to leave the park and smoke in a designated area,” Ms. Jaeger said.
