Unfortunately this can currently not be handled automatically by the booking system. This feature is planned to be added in 2017.
The same is true for these scenarios (not currently supported):
- You want to make two separate but adjacent rooms available as one single bookable unit.
- You want to offer individual beds in a dorm, but at the same time make the whole dorm bookable as one unit.
- You want to offer a conference room for several sessions, but also make it bookable for a whole day.
