Holiday dance (4)
I believe the answer is:
trip
I believe this is a double definition.
'holiday' is the first definition.
(I've seen this before)
'dance' is the second definition.
(I've seen this before)
(Other definitions for trip that I've seen before include "Outing; stumble" , "often occurring just before the fall" , "holiday" , "a result of drug-taking" , "day out?" .)
