@Brian364 Yeah, the Extra Guest: No Charge can be very misleading. On a laptop, go to your Pricing under Manage Listing. Under Extra Charges click Edit. For the Extra Guest amount, be sure it is blank without even a zero. Also make sure the "For Each Guest After" section includes your maximimum occupancy. Be sure to save your change. Let me know if this works.
This is how my listing is set up:
Extra Charge: Blank
For each guest after: 4 (the maximum number of guests I can accommodate)
Please let me know if this works for you!
