They stayed in Room 902 at the Amsterdam Hilton for a week between March 25 and March 31 and invited the world's press into their hotel room every day between 9 a.m. and 9 p.m. After their other stunts, such as the naked cover of the Two Virgins album, the press were expecting them to be having sex, but instead John and Yoko were sitting in bed talking about peace with signs over their bed reading "Hair Peace" and "Bed Peace". The world's press ridiculed them relentlessly, but they didn't allow their peace efforts to be hindered in any way. After seven days they flew to Vienna, Austria, where they held a press conference while eating chocolate cake inside a white bag, which was promoting Bagism, another of their concepts which called for social change.
John and Yoko's marriage, their first Bed-In, the Vienna press conference and their acorn event were all mentioned in the song "The Ballad of John and Yoko".
Their second Bed-In was planned to take place in New York, but John wasn't allowed into the country because of his 1968 marijuana conviction. Due to its proximity to the United States, they decided hold their Bed-In in the Bahamas at the Sheraton Oceanus Hotel. They flew there on May 24 1969, but after spending one night in the 86°F heat, they decided to head to Toronto, Canada.
Eventually they flew to Montreal on May 26 where they stayed in Room 1742 at the Queen Elizabeth Hotel. During their seven day stay, they invited Timothy Leary, Tommy Smothers, Dick Gregory, and Al Capp and all bar Capp sang on the peace anthem "Give Peace a Chance", recorded in the hotel room on June 1.
Their peace campaign was met mostly with derision, and most journalists simply dismissed it as a publicity stunt. Lennon, who was accused of doing this for money or attention, said he could write a song in an hour and make more money off that song then he could spending seven days in bed talking about peace.
