How can I check the Promotion restrictions?
STEP 1: First you need to go to the REVENUE tab and select PROMOTIONS on the bottom left corner of the sidebar.
STEP 2: Click on OPEN/STOP SALES
STEP 3: Above the calendar area, select the promotion you wish to update from the drop down list.
STEP 4: On the specific date you can click on the "i" icon and a window will be displayed with the Promotion restrictions. This can be done on any Promotion.
If the promotion does not have any min/max stay and the room has, it will consider the room's restrictions (most restrictive option).
