We will be flying from Heathrow to Arlanda (Stockholm) on September 5. Our flight lands at 12:30 in the afternoon. We will be going through immigration, getting our luggage and a rental car and driving 2.5 to 3 hours to Finspang to visit a very sick friend and then we fly back 2 days later. Would anyone have a general idea of how long it will take us to take care of everything and be on our way to Finspang (plus do it in reverse 2 days later)? Thanks.
