Disney's Animal Kingdom reopened Na'vi River Journey around 6:30 p.m. Eastern on July 13 after the boat ride stayed down through nearly the entire park day.
CrowdLevels recorded the outage from 7:35 a.m. until 6:30 p.m., a stretch of nearly 11 hours. Posted waits reached 25 and 30 minutes before the park closed at 7 p.m.
The slow-moving Pandora boat ride normally runs throughout the day and has no height requirement. Disney has not announced a reason for Monday's downtime.
