I’d be happy to help you with that!
According to my knowledge, the Atlantis water park in Guangzhou, China has a thrilling attraction called “Extreme Rafting”. This ride is available from Fridays to Sundays. So, no, you can’t play it only on weekends. You can enjoy this extreme thrill during weekdays as well.
Please note: Information may be subject to change. It’s always best to check with the park directly for any updates or confirmation before planning your visit!
