Disneyland Resort temporarily shut down access to both its theme parks Tuesday as holiday crowds pushed Disneyland and Disney California Adventure to capacity.

Park officials had to stop selling tickets for the second straight day at Disneyland around 10 a.m. -– about two hours after the park opened, a park spokeswoman said. Instead, patrons were directed to Disney California Adventure.

But by 1 p.m., both parks were full and Disneyland tweeted from its official account: "Disneyland Resort extremely popular today. Disneyland and Disney California Adventure access temporarily limited."

It was unclear when the parks would resume ticket sales. The week between Christmas and New Year's is traditionally one of the busiest in the parks. Annual pass-holders -– except for the premium level –- are blocked unless they want to pay additional admission.
