"A Christmas Fantasy Parade" was near the end of its route, near the "It's a Small World" attraction, when it hit the four spectators at about 8:15 p.m., park spokesman Rob Doughty said.

Anaheim fire Capt. Jamie Hirsch said the people were hit by the simulated carpet on the Aladdin float.

"Instead of going straight, (the float) kind of turned to the side and hit the four people," Hirsch said. "The float has a piece of carpet that comes off the back. The piece of carpet struck the guests."

Two adults and a child were treated at the scene for minor injuries, Doughty said.

One woman – identified by her sister as Mayra Perez, 34 – was knocked unconscious and taken to Western Medical Center in Anaheim.

"(The float) hit her and knocked her out cold," the sister said while while waiting at the emergency room. "Her face is bruised up pretty bad."

Perez recently immigrated to the United States from Guatemala, her sister said.

Police could not confirm the injured woman's name, but Hirsch said she was discharged late Monday.

Light rain may have contributed to the accident, which is under investigation by the Anaheim Police Department.

"The inclement weather and the fact that the ground may have been wet could have contributed to what happened," police Sgt. Rick Martinez said.

Esther Murillo, 50, of Whittier was watching the parade near Tomorrowland, about halfway along the route, when the procession suddenly stopped for about five minutes.

"The dancers kept (dancing), Pinocchio just kept saying 'hi, " Murillo said.

Her daugher, Jami Murillo, 33, sensed a problem.

"We just thought that one of the floats had broken," she said.

The last accident at Disneyland ocurred in July, when two trains on the Big Thunder Mountain Railroad roller coaster collided, causing minor injuries to five people.

A man was killed on the ride in 2003 when a train crashed in a tunnel.
