Starting May 1, Disney parkgoers in the U.S. will no longer be allowed to smoke or vape inside the company's theme parks.

The House of Mouse said Thursday that smoking areas would be removed from all Walt Disney World and Disneyland parks as well as at water parks and the ESPN Wide World of Sports Complex, according to the Disney parks website.

Designated smoking areas will be available outside of the entrances to these parks.

"As we expand our offerings, we will continue to take steps to enhance the guest experience and make it more enjoyable for everyone who visits," Disney said in a statement Thursday.

In addition, Disney has also changed its guidelines for what types and sizes of strollers are permitted in the park. Strollers wider than 31 inches or longer than 52 inches will not be permitted into the park. The company has also prohibited stroller wagons.

This major change comes as Disney prepares to open new Star Wars-themed lands in California on May 31 and Florida on Aug. 29. Galaxy's Edge is expected to draw huge crowds, and removing these smoking areas will help with reducing congestion within the park.

The new lands in Orlando and Anaheim are set on a new planet called Batuu. It's a thriving port filled with rogue traders, droids and unique alien species. Visitors will be able to pilot the Millennium Falcon and take part in a battle between the First Order and the Resistance in two new rides.
