ORLANDO, Fla. -- Walt Disney World is raising the price of a one-day, one-park ticket to $67, the company announced Friday.

Disney doesn't release attendance figures and declined to comment on why they raised ticket prices for the second time this year.

The $4 increase, which includes entrance to all four theme parks, will go into effect Sunday. The new price will also effect the company's "Magic Your Way" flexible ticket plans, which allows guests to purchase cheaper packages if they stay longer or visit multiple parks.

"The timing of the change falls in line with the needs of the travel trade industry so they can use it to get the most current information for their travel guides," Disney spokeswoman Jacquee Polak said.

When Disney raised its price from $59.75 to $63 plus tax in January, Universal Orlando and SeaWorld Orlando also raised their ticket prices. Price wars have become an annual rite between the three major theme parks.

In January, Universal raised its admission price to $63 and SeaWorld raised its price to $61.95.

A spokeswoman for SeaWorld said they had no plans to raise prices in response to Disney's announcement.

"Our pricing strategies are developed as part of our overall business plan and not as a response to our competitors," SeaWorld Orlando spokeswoman Becca Bides said.

Telephone messages left at Universal were not immediately returned Friday.

SeaWorld is owned by a subsidiary of Anheuser-Busch Cos., and Universal Orlando is part-owned by a unit of NBC Universal Inc., a unit of General Electric Co.
