Most of the scouts spent about eight hours hiking around the area looking for clues to the location of the missing Middleton, according to the Buckinghamshire Advertiser.
The paper quoted event organizer Brian Shelley as saying he did not see anything inappropriate in the rescue-the-princess-themed outing.
"I don't think it was inappropriate," Shelley was quoted as saying. "The scouts loved it and found it very amusing. Nobody raised any concerns on the day, so I'm surprised to hear if there were any."
News of the game angered some local councilors and led to national media coverage.
Messages seeking comment from the 2nd Amersham Common Scouts were not immediately returned Saturday. Buckingham Palace declined comment on the topic of the mock kidnapping.
William and Middleton are being married April 29 at London's Westminster Abbey. The government is expected to deploy a major security presence for the event.
