If you’re dreaming of a theme park trip with your kids, you might worry that you won’t fit into some ride vehicle seats. But you have options -- theme park industry leaders such as Walt Disney World and Universal Orlando have pioneered accommodations including bigger seats and longer seat belts for weight-challenged travelers, and many smaller park operators, such as Cedar Point , are following suit by installing rides with larger passenger-size capacities.Meanwhile, modified seats for larger guests are often available on attractions such as Universal Orlando’s roller coasters. By the ride entrance, you’ll find test seats -- replicas of both a regular and a modified seat -- that allow you to see how you fit before getting in line.Note that on some theme park rides, such as the Magic Kingdom’s Big Thunder Mountain Railroad , a single lap bar protects multiple riders. For everyone’s safety, avoid seating small children beside large adults -- otherwise, you run the risk of having the child slip out of the lap bar that is resting on the adult’s stomach or thighs. On rides with seat belts, the belts tend to lock when you stop pulling them out. To make sure it goes all the way around, pull the belt all the way out to its maximum length before attempting to fasten it.Theater shows do not have restraints to contend with, but many theater seats are tight. An example is La Nouba , the Cirque du Soleil show at Walt Disney World’s Downtown Disney. However, in the United States, wheelchair viewing areas are required by law. At any standard theater show in the United States, theater attendants will bring in a standard chair if you are uncomfortable in the traditional theater seats.
