Prince Harry will complete his one last "summer of mischief" before he celebrates his 30th birthday next month in September and begins his search for a bride.
According to source, things have changed since the 29-year-old royal's 2012 Las Vegas trip, where he was captured on camera playing strip billiards, the Daily Star reported.
The security at the Kensington Palace has become tighter with gadgets like smart-phones and cameras not being allowed inside, added the insider.
The Prince, who split from Cressida Bonas earlier this year, and had been partying hard ever since, blames his fame for his failed relationships, and had told his pals that there would be no such incidents anymore.
