"Being here, it's like my childhood in real life," said Carlos Moctezuma, who wore a Mario outfit to the park.
"I've known Mario since I was in second grade. That was one of my first games on the Game Boy," said his partner Lexsi Houseman, dressed as Luigi.
"It's a dream come true," she added.
STAR-STUDDED CAST
The official launch of Super Nintendo World is set for February 17, when visitors surrounded by mechanical Yoshis, Piranha Plants and Goombas from the beloved gaming franchise will be greeted by actors dressed as Mario, Luigi and Princess Peach.
A third Nintendo theme park will follow in Orlando.
Meanwhile, Universal Pictures -- the Hollywood film studio that shares its parent company with the theme park -- will release "The Super Mario Bros. Movie" in April.
The film features U.S. actor Chris Pratt as the voice of Italian plumber Mario -- a casting choice which has sparked controversy and criticism on social media, but only drawn more attention to the nostalgia-laden movie.
A starry voice cast also includes Anya Taylor-Joy as Princess Peach, Jack Black as Bowser, and Seth Rogen as Donkey Kong.
It will be Hollywood's second attempt to bring Nintendo's most famous characters to the big screen, after a widely panned 1993 live-action movie.
The first "Super Mario Bros" game came out in 1985 for Nintendo's NES console.
The platform game, in which Mario runs and jumps past obstacles to collect coins and save Princess Peach from the evil Koopa turtles, was based on the "Mario Bros" arcade game released earlier.
