WooCommerce Bookings

I need some technical help from you.
I cannot create trip like as given in url
Below are the steps :

Choose product as Bookable.
Then select “has person”

Fro timing create 270 minutes of fixed block.
Make rule to run this trip only may to september.
add timing slot to exclude from 6: 30 PM to 11:59 PM.

Now, consider only below online price.
Online Price A.M.
94.95 Adult, 85.95 Child
Online Price P.M.
89.55 Adult, 80.55 Child

I have added PM time slot to ‘cost option’
to minus 5.4 from 94.95. so it will be 89.55.
when I select PM time price will be 89.55.

But the problem is this works only for 1 person.
If I added 2 person then it will not work proper.
If I choose Child, then it will not given right price.

In short want to set price as per the AM and PM for added person in bookable product.
Can you please help me to solve these type of problem in booking ?
