FrontDesk Master lets you separate High Weekdays and Low Weekdays in case you would like to set different prices for different days of the week. For example different prices for weekends.
In Rates, open the rate and select as High Weekdays the days you would like to have different prices.
Please note that it is not possible to set all days as High Weekdays. If you have the same prices all week, do not select High Weekdays.
You can then set the prices for High Weekdays and Low Weekdays in Prices.
LD are Low Weekdays and HD are selected High Weekdays.
