It is possible to input rates for daily, weekly, 3 week price and monthly prices.
If end user selects a total number of nights <= 7 then daily rate is used
If end user selects a total number of nights between 7 and 21 (>7 and <=21) then weekly rate is used
If end user selects a total number of nights between 21 and 28 (>21 and <=28) then 3 week price is used

The rate calculated is daily usage. Meaning is user selects 8 nights then the total presented to end user is 8*weekly rate inputed
