Amsterdam bed-in

 

Knowing their March 20, 1969, marriage would be a huge press event, Lennon and Ono decided to use the publicity to promote world peace. They spent their honeymoon in the presidential suite (Room 702)[3] at the Amsterdam Hilton Hotelfor a week between March 25 and 31, inviting the world's press into their hotel room every day between 9 a.m. and 9 p.m.
