@Doug-And-Hazel0 Yes to what @Elaine-and-Duane0 said. Open your calendar. Near the upper right, click on Pricing Settings. Carefully ignoring the bad, bad, bad Smart Pricing section, scroll down to the bottom and click on Additional Pricing Options. Scroll down until, below the Cleaning Fee bit, you see a checkbox for Additional Guests. Check that box and proceed from there.
