Hi, Wyman! Welcome to planDisney.
I'm so glad you stopped by with your question. It's always smart to research
what's allowed in the parks before you arrive so you can breeze through security and focus on the fun. Over the years, I've had to become an expert in this, since we usually rock up with a double stroller filled with enough supplies for a week-long campout. So I've had to learn both what I can't bring into the parks and what unnecessarily sets off the metal detectors (sunglasses case, I'm looking at you!).
You're correct that vaping and smoking aren't permitted inside any of the
Walt Disney World theme parks. However, you can bring your vape device through
security without an issue, as long as it stays turned off and stored safely in your bag. Once inside, you'll find designated smoking areas outside the park entrances where vaping is allowed. Security Cast Members are used to seeing these devices, so just be upfront if asked, and you'll be fine.
A little tip for your day: keep your vape in a clear, easy-to-access pocket when going through bag check to make screening quick and simple.
Cheers, Wyman. Have a great trip!
Mike
