Hi @Maryam-Al-Fakheer0
It sounds like you wanted clarification on something that wasn't addressed, but I am still having difficulty understanding what you are trying to do with your settings and the reason for the minimum number of guests.
As far as I can see, the reason to set # of guests, and $XXX charge per guest, is so that host gets paid more when there are more guests.
For instance, if you have a home or apartment that has 4 bedrooms and can accomodate 8 guests (say if there were 2 per bedroom) , but you don't want someone with a party of 4 people to have to pay the same amount that a party of 8 would pay (because they use less utilities and less linens and beds) then you set your price for 4 people as the basic price (so the PRICE Is what is set as a minimum, not the # of people, even though the minimum price includes 4 people) , and if there are more than 4, they pay a higher rate accordingly. The "Extra per person" charge in this case would only apply to extra people over 4. In other words, if you have 1, 2 3, or 4 people, they pay the basic price. BUt if you have 5 people, there is one extra person charge. If you have 6 people, two extra person charges. and so on.
However, if you have a situation where you have just one person who wants to rent this 4 bedroom house, and have it all to himself, all 4 bedrooms, and he is willing to pay the same price that you would charge for 4 people to stay there, I don't see why that would bother you or why you would tell him, "No, the place is for 4 people, minimum." IF you have one person staying there who pays for 4 they will actually use less utilities (less water) and less linens (not as many sheets and towels) and probably leave the place cleaner than if 4 stayed there, so you actually get a better deal when one person wants to rent the whole 4 bedroom home.
Same situation if you rent out rooms with multiple beds, I would think. If you want the minimum price to be for 2 people, then set the minimum price for 2 people, and if one person wants to come and is willing to pay the rate for 2 people, I don't see why that would be a problem for you.
It really seems that what you want is a minimum charge, not a minimum number of guests. If I am missing something, can you explain what I didnt' understand?
