represented them. At the end of this final boot camp round, 32 acts would go through to judges' houses. This final performance was done in front of a crowd of 3,000 people. After each of the performances, the judges gave no feedback. The first boot camp episode aired on October 5, 2011 and covered the first two days of boot camp. The second bootcamp episode aired on October 6 and covered the rest of day two and the remainder of bootcamp. By the end of bootcamp, 162 acts were cut to 32, 8 acts in each category. The judges later found out which category they would mentor and their acts joined them at their house. Judges' houses Enrique Iglesias helped Scherzinger select her finalists in Malibu, California and Pharrell Williams acted as a guest judge helping Abdul to pick her finalists in Santa Barbara, California. Rihanna helped Reid choose his finalists in The Hamptons, New York. Mariah Carey was contracted to aid Cowell in France, but was unable to attend due to Hurricane Irene grounding her flight to Paris, so Cowell was instead assisted by three vocal coaches. In the United States, footage from judges' houses was originally scheduled to air on October 12, 13 and 18. However, due to weather delaying the start of the 2011 American League Championship Series, the footage from judges' houses 1 was moved to October 13, with footage from judges' houses 2 seen instead on October 16. The footage from judges' houses 3 aired on October 18 as scheduled and featured footage of the judges revealing their four finalists (or five in the case of Cowell) in each category to take through to the live shows. In Canada, the judges' houses 1 episode was broadcast as originally scheduled on October 12. No episode was shown in Canada on October 13, with CTV and CTV Two opting to follow Fox's scheduling changes to take advantage of simultaneous substitution rules. {| class="wikitable plainrowheaders" |+Summary of judges' houses |- !
