The price offered to the guest will be the lowest from your DAILY PRICES and your RATES which match the requested stay period.
===Set a refined flexible rates and discount structure===To set a defined flexible structure go to RATES in the top menu. Multiple rates and discounts may be defined for each room. When multiple rates exist for a given date the system default will calculate and offer the lowest price that matches your criteria. You can override this in the rates settings.
When creating multiple rates you would generally set your highest price to always be available and create discounted price rates for longer stays, specific days of the week or date ranges as you require. This way you can create sophisticated rate models.
