Most miserable in Spain, het up when travelling (10)

Ross

I believe the answer is:

unhappiest

'most miserable' is the definition.
('unhappy' can be similar in meaning to 'miserable')

'spain het up when travelling' is the wordplay.
'when travelling' indicates an anagram.
'spain'+'het'+'up'='spainhetup'
'spainhetup' anagrammed gives 'UNHAPPIEST'.

'in' acts as a link.

I've seen this clue in The Telegraph.
