Harry and Meghan can throw a Party on Oscar Night in Hollywood, like "Night of 100 Stars" that Norby Walters used to produce, and they can raise money for Children of the Night. They can throw the party at the Park Plaza Hotel in Los Angeles, and they can have an outdoor bar at MacArthur Park, etc.
Harry and Meghan can also throw a Party at the Cannes Film Festival in the South of France to raise money for Children of the Night in Hollywood.
A Prince and an Actress, they should be able to throw good parties, they can raise money for Charity by partying and socializing and by having fun.
Salute,
Tony V.
