If you think that “mandatory quarantine” means “lightly suggested period of slightly heightened social distancing” that isn’t actually enforceable, you’re wrong. Hawaii requires a mandatory 14-day quarantine for anyone visiting the state, and violations of that rule could result in jail time.
On April 30, 2020, according to local authorities, a California couple on their honeymoon ignored the requirement to remain in their hotel room, and after several warnings by hotel staff, were arrested by police. A few days earlier, on April 28, another couple was similarly arrested by Honolulu police after breaking quarantine. Once hotel staff noticed them returning to their room with shopping bags and takeout food, they alerted the authorities.
