ANAHEIM, Calif.–Overcrowding forced Disneyland and Disney’s California Adventure theme parks to turn people away at the gates today.

“Disneyland Resort is extremely popular today due to holiday offerings. Disneyland park access is temporarily limited,” park officials announced via a Twitter post about two hours after the park opened today.

Patrons were directed to California Adventure, but that park reached capacity about three hours later.

It was unclear when–or if–ticket sales would resume and more people would be admitted to the parks. The holiday week is traditionally one of the busiest times of year for the theme parks.

Disneyland had a similar overcrowding problem Monday and stopped admitting people to the park.
