💬 What Parents Say

  • 💡Plan your visit around planetarium and submarine tours, which are the most popular attractions—arrive early or check show times in advance, as planetarium laser shows have long lines and run only periodically
  • 💡Consider purchasing a membership if you plan multiple visits, especially for homeschooling families; reviews indicate the membership provides strong ROI with frequent visits and access to special events
  • 💡OMSI is specifically designed for children and families with hands-on interactive exhibits and a dedicated toddler area; note that adult-only visitors may find the experience less engaging based on visitor feedback
  • 💡Check ahead which exhibits are open before your visit, as the upper floor exhibits frequently have closures; visit during OMSI After Dark events or when special traveling exhibits (like Studio Ghibli) are featured for a more unique experience
  • 💡Plan for extended hours and bring your own snacks or arrive when food trucks are present, as on-site food options are limited; many exhibits offer hands-on learning stations that work best with unhurried exploration time
