Room types need to be fully configured
1. Go to Hostelworld Room Type configuration and fill in all the fields.
2. Once this is done return to myallocator mapping page and map the room.
3. If the room isn't in the list please contact Hostelworld to ask them to enable this room type for channel management.
In the example below Room Grade wasn't set up so the room wasn't available for mapping in myallocator.
