ANAHEIM Disneyland stopped admitting new guests for about 90 minutes Friday afternoon because of overcrowding.

“Many guests are enjoying the parks today,” park officials said on the site’s Twitter account at 1:15 p.m. when it announced the closure.

The park re-opened at about 2:45 p.m. California Adventure Park remained open throughout.

During the closure, guests who had already been in Disneyland but had left the park were readmitted.

Attendance numbers were not disclosed.

“With additional entertainment offerings, we are working to accommodate all of our guests,” Melissa Britt, a Disneyland Resort spokeswoman, said in an email.

Disneyland closed last year on Christmas Day after reaching maximum capacity.

Christmas is typically one of the busiest days of the year for the theme parks. Except for those with its highest-level passes – the newer $1,049 Signature Plus and its older Premium Annual passport – Disney does not allow people to use annual passes to enter the parks on Christmas.

Disney changed is pricing structure in October, adding the Disney Signature Plus (the only still sold with no blackout dates) and the Disney Signature, which costs $849, and raised its prices for lower-tier annual passes by as much as $60.

More than 16.7 million people visited Disneyland and another 8.7 million visited Disney California Adventure in 2014, according to The Themed Entertainment Association, a trade group that represents members of the theme park industry. Disney officials won’t divulge attendance numbers or when the busiest days are.

According to Robert Niles, editor at ThemeParkInsider.com, the days after Christmas leading up to New Year’s are always the busiest at Disneyland.

At what point Disneyland temporarily shuts its gates – to balance letting in a lot of people without allowing the park to get too crowded by Disney standards – is a mystery to outsiders.

Britt said Disney’s procedure to temporarily stop admitting guests happens “infrequently.” Several annual pass holders have said it usually happens on holidays such as the Fourth of July, Christmas, New Year’s Eve and when the park is open for 24-hour celebrations.
