To take bookings for a dorm or other shared room, you need to set up each bed as a 'Room':
- Create a new room
- Call it 'Bed in shared dorm' (for example)
- Set 'Describe as:' to 'Bed'
- Enter the price and other details
- Check the box 'I have several like this' and set the number of beds that you have
- Guests booking online will be assigned to the first available bed
