Hello Catherine and welcome back to the Disney Parks Moms Panel!
You are correct, as of May 1, 2019 smoking is not allowed inside any of the Walt Disney World Parks. Smoking is allowed in specified locations outside of the parks. There is a
map located here on the Walt Disney World website the indicates where the smoking areas are located.
All Walt Disney World park tickets allow guests to leave and re-enter the park on the same day. So, no matter what type of
theme park ticket you hold, you should have no problem returning to the park if you need to leave.
I hope this helps with your planning. If you have more questions, come on back to the Disney Parks Moms Panel. We love to help!
See ya real soon,
Anne
