I’d be happy to help you with that!
According to my information, the park’s exact opening date for 2024 has not been officially announced yet. If you’re looking for precise details about their 2024 schedule or any specific updates, I recommend checking the park’s official website, contacting them directly through email or phone, or visiting a local tourist information center.
However, as of now (August), it seems unlikely that the park would suddenly open on August 18th without prior announcements.
