Places to stay from Carlisle to Harrogate when retired (6)
I believe the answer is:
hotels
'places to stay' is the definition.
(I've seen this before)
'from carlisle to harrogate when retired' is the wordplay.
'from' indicates a hidden word.
'retired' shows that the letters should be reversed in order.
'sletoh' can be found hidden inside 'carlisle to harrogate when'.
'sletoh' in reverse letter order is 'HOTELS'.
(Other definitions for hotels that I've seen before include "Lodging houses" , "Establishments providing rooms and meals" , "Ritz and Hilton are" , "Inns, lodgings" , "Buildings for travellers" .)
