Compare the whole booking
List transport, admission, food, equipment and any optional extras before comparing totals. A tour with a lower headline price may leave you to pay for the stop you care about; an expensive private trip may still spend most of the day driving if the route is too ambitious.
Read the named itinerary and recent visitor descriptions for practical details. Separate an operator’s general scenic tour from a trip that specifically explains the filming connections. Neither should imply that surviving props, actors or a studio visit are included unless the operator explicitly provides them.
Ask one useful question before booking
“How long do we actually stop at the Lough Tay viewpoint, and what happens if weather or road access prevents that stop?” The answer tells you more than a list of filming names.
