Create seasons with minimum nights, set a nightly price for each configuration and block the dates that are not available.
A rental's price depends on the season and the configuration the guest picks. In Skyrez you create the seasons and then fill in a table with the nightly price for each combination.
Before setting prices you need at least one configuration. See Create your rental property and its configurations.
In My Properties, click Configure on your property and open the Seasons & Rates tab.
Click Add next to Seasons and fill in:
Click Save. Repeat for all your seasons and make sure they cover every date you take bookings for.

Under Nightly rates there is a table: each row is a configuration and each column a season. Enter the price per night in each cell and click Save rates.

If a stay spans two seasons, the widget charges each night at its season's rate and shows the guest the breakdown and the estimated total. If the chosen dates have no rate, the widget says the host will send the price upon confirmation. That's why your seasons should cover every date you rent.
On the property page click the Blocks tab (or Block dates from My Properties).
On the calendar, click the first day and then the last day you want to block. Add a Reason if you like (for example "Maintenance" or "Direct booking") and click Block.

Blocked dates can no longer be picked in the widget. To free them, delete the block under Active blocks.
You don't need to block the dates of your requests: pending and confirmed requests already take up the calendar automatically.
