During the Zoom call, Barry Williams, Christopher Knight, and Mike Lookinland are in the same order on the right-hand side as they were in the "Brady Bunch" credits.
Robbie Rist, who plays front-desk clerk Sheldon, played Cousin Oliver on "The Brady Brunch."
The dedication before the end credits: "In loving memory of Dr. Howard Sokoloff," is for the father of director Marla Sokoloff.
During the Zoom call, Jennifer Elise Cox (who played Jan in the Brady movies) and Susan Olsen are not in the correct order on the left side as they were in the "Brady Bunch" credits. The kids were all stacked in descending order of age, so Susan Olsen was always in the bottom left position.
During the Zoom call, Jennifer Elise Cox (Jan in the Brady movies) complains that Emma's mother, Michelle, did not tell her of the impending engagement, by saying "Michelle, Michelle, Michelle", which is a reference to Jan complaining about "Marcia, Marcia, Marcia" in one episode of the original "Brady Bunch" series. Susan Olsen, on the iPad during the proposal scene, repeats the refrain with "Laura, Laura, Laura".
