Leah protests the idea of attending a theme park pretending to be a toddler. She might get in free, but she won't be able to ride anything fun! Tina points out that due to her height, Leah couldn't ride anything meant for someone older than a toddler anyways. If she dressed like a teenager, she'd get weird looks and might not be allowed to do the toddler or baby activities, leaving her unable to do anything. But this way, she can at least get on toddler rides.
Leah nods reluctantly, as that was her last experience at a theme park. Too old for toddler things, too small for anything else. If she has to wear a diaper to enjoy herself, so be it.
The drive to the theme park, Trolly Land, takes eight hours. Leah spends the entire time in a car seat, wearing only a diaper and T-shirt. They stop for gas and a bathroom break once, during which Leah's dad, Robert, checks her diaper and announces she's wet. Leah blushes, humiliated. Robert was loud enough for the entire gas station to hear. Her blushing gets even worse when Tina changes her in the car, in full view of anyone walking by.
"We have to get back on the road as fast as possible," Tina hisses to Leah when she complains. She stuffs a pacifier into Leah's mouth to keep her from talking more.
Four hours later, Leah wakes up as they park at the resort inside the theme park. Her diaper is thoroughly soaked, but she's excited to have finally arrived. They walk into the resort lobby, Leah waddling from her thick and wet diaper. Leah looks around excitedly. She can't wait for their first activity!
