How you set up the minimum night restrictions will depend on whether your channel manager supports this function on Hostelworld Website or not.
At the moment Myallocator, ASSD, Availpro, Avirato, Parity Rate, Yield Planet, SYHA, SabeeApp, Octorate, EZEE and Dorm Project channel managers are able to support this, so you should be able to load min night restrictions directly though the channel manager. Please inquire with your channel manager support if this needs to be activated on your profile.
If you are updating minimum night stay in Inbox directly, please make sure to disable the minimum night stay updates in the channel manager, as otherwise your Inbox entries might get overridden.
