John Shaw who played the hotel manager, previously appeared in the episode Long Distance Call (2008), as "Ben Waters".
The name of this episode takes the same name as the animated series from the 80s, The Real Ghostbusters (1986), which was a spin-off of the movie, Ghostbusters (1984).
The episode was filmed at the Stanley Park Pavilion, a former concession stand originally built in 1913. It has since been expanded and was renovated in 2014. It can be rented out for banquets, parties, weddings and, of course, film shoots.
