Space ritual is a hotel facility (4,7)
I believe the answer is:
room service
'a hotel facility' is the definition.
(I've seen this before)
'space ritual' is the wordplay.
'space' becomes 'room' (enough space or room to do something).
'ritual' becomes 'service' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'room'+'service'='ROOM SERVICE'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for room service that I've seen before include "what lazy guests may request?" , "hotel catering" , "Hotel's internal delivery" , "Provision of food privately to hotel guests" , "Hotel internal delivery" .)
