Before heading to Walt Disney World for a day full of fun at the “happiest place on earth,” make sure you’re familiar with some of their latest rule changes.

Effective as of today, new regulations include topics such as smoking, strollers, stroller-wagons and loose ice, according to the Disney Parks Blog.

Starting May 1, 2019, smoking areas will be nonexistent inside of Walt Disney World and Disneyland theme parks, water parks, ESPN Wide World of Sports Complex and Downtown Disney in California. There will be designated smoking areas outside of the entrances of the theme parks and other areas affected, such as Disney Springs in Florida. There are also smoking areas available for guests who have room or dining reservations at Disney Resort hotels.

Strollers play a major role for families throughout a day at Disney World. They can serve as a napping area, a way to store all of your stuff and a spot for the little ones to rest their legs while you’re making your rounds at the parks. As of May 1, 2019, the guidelines for stroller sizes are changing and strollers cannot be any bigger than 31 inches wide and 52 inches long. A majority of the strollers sold today, even the double jogging strollers, fit within these guidelines.

As of May 1, 2019, wagons and stroller wagons will no longer be permitted in the parks. Disney Parks Blog says this will help ease congestion to make the parks more enjoyable for everyone.

And as always, you can rent a single or double stroller during your time at the parks.

Starting today, if you bring a cooler to store snacks and drinks for your day at the parks, loose or dry ice are no longer permitted. Disney Parks Blog suggests keeping your snacks and drinks cool with re-useable ice packs instead. You can also visit any Quick-Service location for complimentary cups ice for your cooler. You can always request complimentary cups of ice water to stay hydrated while moving through the parks.
