Ferrari World is a lot of fun.
Enjoyment: Surprisingly, there are quite a few attractions for children under 110cm tall.
The park also has a small playground where children can climb freely, which keeps them entertained for hours.
Temperature: Although the park is located on the second floor of Yas Mall, the space is naturally light-filled, so it's quite warm inside. Even wearing summer clothes won't be a problem; you won't feel cold.
It's much warmer than Warner Bros. and SeaWorld, haha.
Convenience: There's a direct shuttle bus from Yas Island to Ferrari World.
Dubai also has a direct shuttle bus to Ferrari World, both of which are super convenient.
Note: You can bring food and water into the park. This is very user-friendly.
However, I'm not sure what their criteria are; each park on Yas Island has different rules. If you find something that's not allowed, you can either throw it away or check it in.
I tried bread, snacks, and plastic bottles of water, and they were all allowed.
