If you are hirinb a car , you may stay in a caravan or a trailer as in usa, parkdean sites you can book for 3 and 4 nights at different sites over Scotland, or MacDonald hotels used to do deals for staying at different hotels in the chain at a reduced cost . Also you may find smaller hotels with sister hotels dotted about with deals . If not plan out by looking at public transport . If in Edinburgh try to see the underground dwellings which may be of interest . Have fun
