premise: The flights out there and back were n't terribly fun , as you can imagine . ( 18-month - old + 5-hour - plane - ride = very tired parents ; change it to a solid 18 hours total travel to get back , and we were just grateful we all made it to our apartment in one piece . ) However , once we arrived it was absolutely wonderful . The timeshare was on Kauai , the oldest island that tourists are allowed on . What 's one major reason why they were tired ?
hypothesis: Their timeshare was on Kauai .
