Party guys on vacation - they go where they like! (4)
I believe the answer is:
dogs
'they go where they like' is the definition.
The definition suggests an adverb but the answer is not.
'party guys on vacation' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'on vacation' suggests removing the centre (after the inside letters have vacated the word).
'guys' with its middle taken out is 'gs'.
'do'+'gs'='DOGS'
Can you help me to learn more?
(Other definitions for dogs that I've seen before include "Setters, for example" , "pets" , "log hearth" , "Shadows" , "Persistently follows" .)
