Shooting for "Booze Cruise" was a departure from the norm of the series: For one thing, the majority of the episode was filmed away from the Dunder Mifflin set. For another thing, the episode was not filmed during the day, but rather during the night, from 6 p.m. to 6 a.m. Principal filming took place in Long Beach Harbor, California. Because the episode took place on an actual boat, many cast members got sea sick. Rainn Wilson grew especially nauseated on the second night, and Jenna Fischer and David Denman felt nauseated on the last night of shooting. During the final sound mixing for the episode, Daniels recalls yelling at the shot of Jim and Pam on deck. He noted that he had "seen it many, many times, but I was yelling, 'Do it, you idiot! Kiss her!'"
