You have 3 listings.
- for 2 guests - same price for 1 or 2 guests
- for 2 guests (although you mention in title 4 can sleep) - same price for 1 or 2 guests
- for 16 guests.
This is listing is not setup correct: 1 or 2 guests cen rent the WHOLE guesthouse for $41,- / night. You have set a $ 18,- for each guest after the second, but they must be all in same party. It calculates correct. $295,- a night for 16 people. Seems no bug to me.
(But cleaning fee is same for 1 or 16 guests......)
If you want to offer the rooms separately, you need to create a listing for each room (or for any combination of it you wish to offer). Then link the calenders.
