Tickets to Disney’s Magic Kingdom theme park have been bumped up to $105—the first time the price has breached $100.

The increase comes as no surprise, as Florida’s Magic Kingdom, along with every other major theme park, generally raises its admission price each year. “There is strong demand for our attractions and entertainment,” a Disney (DIS) spokesperson said in a statement.“We continually add new offerings and experiences, and many of our guests select multiday tickets or annual passes, which provide a great value and additional savings.”

Still, there’s no doubting just how expensive Magic Kingdom’s ticket prices have become. When the park opened in 1971, tickets cost only $3.50, or about $20 in 2014 dollars. Ticket prices have more than doubled in the last 13 years alone.
