Questions related to rates rules
How does the rate engine work if I have several times the same rule?
(ex. "Booking less than 10 days ahead" + "Booking less than 3 days ahead")
The way the engine works is to first sort by scope, so specific period/season rules are picked before the global ones, then for the same scope, the rules are sorted from top to bottom. So you should have first the rule Booking less than 3 days ahead and then Booking less than 10 days ahead defined for the same scope to work as expected.
