@Jo740 From what I can see smart pricing isn't very smart. It doesn't seem to recognise holidays (school or Christmas for instance) but rather relies on booking rates/views in the locality to adjust prices. It also seems to reduce pricing the closer it gets to the nights in question. As a result a number of bookings will be made before the algorithm adjusts the price.
The worst thing however is you can't seasonally adjust the min and max prices or adjust them for weekends. This alone makes it very dangerous to use.
