For instance, at present we only allow a minimum of three nights to booked for reservations that are several months in the future.

We would like to still be able to sell two nights, so that we show up when guests search for those dates, but we want to be able to charge almost as much for two nights in that scenario as we would for three.

For example.

Let's say we charge £500 a night.

If a guest booked June 1 to June 4, it would cost them £1500 for three nights.

We would like to be able to charge more than £500 a night if a guest were to only book June 1 to June 3. So it would cost the guest something like £700 a night for a far out booking for two nights.
