Hi, I'm planning a 4-day trip with my parents to Hokkaido in early November. We'll be renting a car from Sapporo and going to a few places. We will arrive at our last stop, which is Hakodate, on Nov 7 afternoon and fly out of Hakodate on Nov 8 afternoon. We plan to visit Motomachi, Kanemori warehouse, Mt Hakodate night view and Hakodate morning market. Our hotel is near Horaicho station (close to Motomachi) and the airport shuttle bus stops near our hotel.
Question: Since we're arriving in Hakodate by car, should we keep the car and get around Hakodate and to the Hakodate airport by car? Or should we return the rental car on the day we arrive in Hakodate and use public transport to get around Hakodate and to the Hakodate airport?
