A family of four (parents, a 4-year-old and a 3-year-old) traveled from Kanagawa Prefecture to Suzuka Circuit Park in Mie Prefecture for a two-day, one-night camper van trip. They used the '3rd Birthday Debut Invitation' plan, which offers free admission for the child within one month after their third birthday and half-price admission for accompanying family members. The trip included overnight stays in the camper van en route and visits to the park.
