You can still use discounts with Beyond Pricing, including those, for example, which relate to length of stay. You could offer a discount on a 7 night stay, for example.

It is advisable however to think carefully about the discounts that you are using, and whether they are really necessary.
In most instances it is better to let Beyond Pricing do its work of calculating the best price for any date booked. Beyond Pricing will have already taken account any seasonal and/or market conditions when setting the price.
The real-time fluctuation in the price set by Beyond Pricing could be viewed as an ongoing, fluid discounting system, which allows a more flexible approach than blanket discounts.
