Get me busy travelling? Please continue (2,2,5)
I believe the answer is:
be my guest
'please continue' is the definition.
(phrase used to give someone permission to continue)
'get me busy travelling?' is the wordplay.
'travelling?' indicates an anagram.
'get'+'me'+'busy'='getmebusy'
'getmebusy' anagrammed gives 'BE MY GUEST'.
(Other definitions for be my guest that I've seen before include "Help yourself!" , "Please do!" , "Go ahead" , "do stay with me" , "Do as you wish!" .)
