Walt Disney Co.-owned theme parks in Paris and Hong Kong are doing “extremely well” compared with a year ago, thanks in part to the weaker U.S. dollar, Disney’s Chief Executive Robert Iger said at a press event in New York.

The weakness of the dollar, which dropped to a record low against the euro in last month, is also helping boost tourism in the U.S. as middle-class families visit Disney World and Disneyland instead of traveling overseas, Iger said.

Iger also said advertising revenue is “pretty robust” given the current economic environment.

“We haven’t seen much effect on the advertising side,” Iger said. “The two primary ways that this company is typically impacted by the economy are advertising and travel/tourism.”

Disney is currently conducting a $1.1-billion makeover on its California Adventure park and is building a Hawaiian time-share and condo resort.

Disney said in its annual earnings that 27 percent of its total sales and 20 percent of its revenue come from ads.

Shares in the Burbank-based entertainment company closed down 1.4 percent to $31.07 Tuesday.
