Those travelled, having left places to stay (6)
I believe the answer is:
hotels
'places to stay' is the definition.
(I've seen this before)
'those travelled having left' is the wordplay.
'travelled' indicates anagramming the letters.
'having' means one lot of letters goes inside another.
'left' becomes 'l' (common abbreviation).
'those' anagrammed gives 'hotes'.
'hotes' enclosing 'l' is 'HOTELS'.
(Other definitions for hotels that I've seen before include "Establishments providing rooms and meals" , "Establishments for travellers" , "Inns, lodgings" , "Places to stay" , "Lodging houses" .)
