In honor of National Grandparents Day on September 7, OUTRIGGER Resorts & Hotels today unveiled The Grandparent Guarantee – the next bold evolution of The OUTRIGGER Promise. Rooted in Hawaiian values and designed for one of today’s fastest-growing family travel movements: skip-gen vacations – where grandparents and grandchildren set out on adventures together – the pledge celebrates kūpuna (elders) and the timeless tradition of strengthening familial bonds.
