If in peak season you wanted to close out your rooms on a Saturday or bank holiday to OTA's but remain available on your own website, this is easy to achieve in Caterbook.
For all Rateplans that are mapped to OTA's, there is an "OTA Restrictions" row underneath the pricing. This allows you to close out rooms on a per rateplan basis - for example not selling Room Only but leaving Bed & Breakfast on open sale.
