Simple! Here's how you do it:
1. Head to 'More' and under 'Profile' you will be able to see 'Add Holiday' option
2. Click 'Add Holiday' and let us know from which day to which day you are occupied :) That's all!
Please note that once you have saved the holiday, all your bookings that are affected will be cancelled immediately and the customers will receive a notification. Please update this carefully!
