Yes, a real-life prince is coming to the Magic Kingdom – and Prince Harry is eager to check out some of the fun during downtime from his Invictus Games.

But it’s not his first time visiting Walt Disney World – and in this week’s exclusive cover story, he tells PEOPLE about a funny memory from his earlier visit.

In 1994, when he visited Orlando, Florida, with big brother Prince William and his mother Princess Diana, Harry was an impetuous and daring theme-park enthusiast.

“We went around Space Mountain 12 or 14 times, so much so that my policeman had to get off and vomit over the bench!” he says. “When you are that age you are invincible. And you slowly become uninvincible as you start breaking things!”

This time around, he says, “I hopefully will be able to go to Disney World and have some fun on the rides without causing too much of a stir. I might go in a costume, maybe get my photograph with Mickey.”

Harry is in Orlando for about a week as he brings his paralympic-style Invictus Games to the U.S., with more than 500 service members from 15 countries around the world set to go head-to-head.

And he tells PEOPLE he’s excited for what’s ahead in the games that kick off on Sunday. “I’m looking forward to using that American style of doing things – that emotion, that fun factor – to try to bring Invictus to even more people and encourage people to come along and see the games. ”
