At Naples? That might be enjoyable (8)
I believe the answer is:
pleasant
'enjoyable' is the definition.
('pleasant' can be similar in meaning to 'enjoyable')
'at naples? that might be' is the wordplay.
'that might be' indicates anagramming the letters.
'at'+'naples'='atnaples'
'atnaples' with letters rearranged gives 'PLEASANT'.
(Other definitions for pleasant that I've seen before include "Nice, satisfying" , "Enjoyable, nice" , "Charming" , "Enjoyable, agreeable" , "Delightful" .)
