Mike and Kathy Frias had no idea when they strolled into The Adventuredome at Circus Circus today that they had just become the 20 millionth visitors to the popular Las Vegas theme park. They had just arrived at Circus Circus by car from Anaheim, Calif., with their children Jose, 13, and Breeanna, 5.

"We are so surprised," said Kathy Frias. "We've never won anything before. Jose wants to go on the roller coaster and Breeanna likes the bumper cars." After being presented with a ceremonial key to The Adventuredome, the Frias' were told their entire visit to Circus Circus would be free of charge.

Mike Frias said, "This is our first time in Las Vegas. I hope I do as well at the slots as I have here in The Adventuredome!"

The prize package also included a tote bag of theme park memorabilia, FREE All-Day Rides passes, plush stuffed Midway animals and a complimentary meal.

"They're staying here at Circus Circus, so we are taking care of everything", said Tom Nolan, Adventuredome Manager of Theme Park Operations. "And they own The Adventuredome for the rest of the day."

When asked about reaching the record milestone, Nolan responded, "People come to Circus Circus to have fun and get away from it all. With 19 rides and attractions packed under the dome, we provide an atmosphere that allows them to do that."

The Adventuredome at Circus Circus is open 365 days a year and is America's largest indoor theme park. In addition to welcoming their 20 millionth visitors today, the vast domed attraction celebrated its eighth anniversary this past summer.

In 2000, The Adventuredome was ranked 19th in visitor volume among North American theme parks by Amusement Business, a well-known theme park industry trade publication. AB also ranked The Adventuredome 34th in visitor volume among all theme parks in the world.
