Abstract: A computer implemented method of allocating costs of a rentable unit across two or more users includes the steps of: assigning two or more users to an event; assigning a date range to the event; assigning a rentable unit to the event, wherein the rentable unit includes two or more heterogeneous sleeping areas and a total price for the assigned date range; assigning a sleeping area to each of the users; and allocating a sub-total to each of the users based on relative value of the assigned heterogeneous sleeping area, wherein the sum of the allocated sub-totals equals the total price of the rentable unit for the assigned date range.
