There are three hotels in the entire Shinhwa World park.
Stay at any Shinhwa World hotel and get free tickets.
You can enjoy three Shinhwa World rides with your Shinhwa World ticket.
Opening hours: 10:00 AM - 6:00 PM.
On rainy days, many rides aren't open, so you won't be able to upgrade to unlimited rides.
The park isn't big, so I only enjoyed two indoor attractions: the hilarious bug ride and the carousel. (The manual allegro music was incredibly labor-intensive.)
Also, you need to purchase a separate ticket for the water park.
Although there aren't many rides, the experience is great, with no lines, vibrant colors, and plenty of photo opportunities.
