Get away from YHA, travel lodges (2,3)
I believe the answer is:
my hat
'get away' is the definition.
(both are exclamations of disbelief)
'from yha travel lodges' is the wordplay.
'lodges' says the answer is hidden in the clue (the answer is lodged within the clue).
'MY HAT' is hidden in the letters of 'from yha travel'.
(Other definitions for my hat that I've seen before include "I refuse to believe" , "Old-fashioned exclamation" , "Exclamation of surprise" , "Out of respect I might remove this" , "nonsense" .)
