You may wish to offer certain booking extras on a seasonal or date-limited basis, for example, firewood, an outdoor pool or BBQ hire. 

To do this, when first setting-up your booking extra, select either 'Standard- by month or no restriction' or 'Advanced- by exact date' depending on how specific your date window needs to be. 

Then, in the 'Booking Extras of each individual property, you can either set a monthly restriction (highlighted in yellow in the image below), which is the span of months that you wish that extra to be offered (i.e. Sept to April), or, if you chose 'Advanced- by exact date' when setting-up the extra, you can click the blue text to set your exact dates.
