Pre sale question

Hi,

I have a presale question before to buy the subscription for to get the plugins that I need

I have to deal with a situation with these constraints:

Check in / Check Out
I have to force the check-in date to Friday and the check-out date to Monday.

Availability is a yes weekend and one not.

Prices
I have a base rate per room (eg triple room = €1200, double = €800, single = €500)
I have a base rate for adult occupant (eg €100)
I have a base rate for child occupant (eg €50)

To get the total price I have to:

divide the rate of the room for the number of occupants
add to this result the base price of the adults or children to get the price per person
add up the price per each person to get the total

Example of a booking of 2 adults + 1 child:

1. €1200 (base rate for triple room) / 3 occupants = €400

2. add to this result the base rate of the adults or children to get the price per person:
Adult 1: €400 (base rate Triple room / 3 occupants) + €100 (adult rate) = €500 (the price for one adult in a triple)
Adult 2: €400 (base rate Triple room / 3 occupants) + €100 (adult rate) = €500 (the price for the second adult in a triple)
Child: €400 (base rate Triple room / 3 occupants) + €50 (child rate) = €450 (the price of the child in a triple room)

3. So I have to add up the price per person of each occupant to get the total price: €500 + €500 + €450 = €1450

Can I get this result using Solidres with the needing plugins?

Regards
