European travel: journey is a gratifying experience (3-4)

I believe the answer is:

ego-trip

'a gratifying experience' is the definition.
(an ego trip gratifies or pleases you)

'european travel journey' is the wordplay.
'european' becomes 'E' (abbreviation e.g. EU).
'travel' becomes 'go' (synonyms).
'journey' becomes 'trip' (trip is a kind of journey).
'e'+'go'+'trip'='EGO-TRIP'

'is' acts as a link.

I've seen this clue in The Guardian.
