Holidaymaker's first turning to the Spanish inn (5)
I believe the answer is:
hotel
'inn' is the definition.
(I've seen this before)
'holidaymaker's first turning to the spanish' is the wordplay.
'holidaymaker's first' becomes 'h' (1st letter of 'holidaymaker').
'turning' says the letters should be written backwards.
'the spanish' becomes 'el' ('the' in Spanish).
'to' in reverse letter order is 'ot'.
'h'+'ot'+'el'='HOTEL'
(Other definitions for hotel that I've seen before include "Place of board and lodging" , "Accommodating establishment" , "posada, perhaps" , "Overnight accommodation" , "Lodging establishment" .)
