Pleasure trip that's revealing (6)
I believe the answer is:
outing
This clue is a double definition.
'pleasure trip' is the first definition.
('outing' can be a synonym of 'pleasure trip')
'revealing' is the second definition.
(outing is a kind of revealing)
'that's' is the link.
(Other definitions for outing that I've seen before include "Day trip" , "Expedition" , "Revealing orientation" , "Excursion as for picnic" , "Excursion, trip" .)
