'vacation?' is the definition.
(vacation is a kind of leisure)

'going back with son's holding attraction' is the wordplay.
'going back with' becomes 'ei' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'holding' is an insertion indicator.
'attraction' becomes 'lure' (lure is a kind of attraction).
'ei'+'s'='eis'
'eis' placed inside 'lure' is 'LEISURE'.

'that is' acts as a link.
