Harry has now returned to Orlando, Fla. to host his Invictus Games — an international Paralympic-style multi-sport event for wounded, injured or sick armed services personnel — from Sunday, May 8 through Thursday, May 12.
"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 Mouse," Harry said.
