Associate rates with capacity, Not possible?

[rulez22]

I have a situation which don't think possible to achieve with PHPR.

My maximum capacity of the apartment is 6
Two rates:
1)one rate if there is 1-2 people staying
2)3-6 people then it's different rate

How do I do this?
I created two rate types, but on the booking page people can select "number of people per apartment" - 6 and rate type "up to 2 people in apartment"
It is not "fool-proof" system. Is there a way to set this up?

Either use the "per person" option for rates or don't ask at all the number of people (it can be inserted automatically with assignment rule n. 4).
