Some of the stuffiest areas for a holiday abroad (6)
I believe the answer is:
fiesta
'holiday abroad' is the definition.
'fiesta' can be an answer for 'holiday' (I've seen this before). I'm not sure about the 'abroad' bit.
'some of the stuffiest areas' is the wordplay.
'some of' indicates a hidden word.
'FIESTA' is hidden within 'stuffiest areas'.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for fiesta that I've seen before include "Elaborate public party, in Spain perhaps" , "Feast day" , "public event abroad" , "Spanish party" , "Festival, fete" .)
