Buildings for travellers (6)
I believe the answer is:
hotels
'buildings for travellers' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hotels that I've seen before include "Ritz and Hilton are" , "Places to stay" , "Establishments providing rooms and meals" , "Lodging houses" , "Inns, lodgings" .)
