We visited 4 exhibitions in two days, what a fun experience. The kids loved lego and science exhibition very much.
Pros:
Lego exhibition has lots of lego models and a play area. The kids really love it.
Science exhibition machines are lots of fun, educational and playful. I wish the schools could have those machines when I was a student. lol. But anyway, never late to learn.
Dinosaurs exhibition there are few large ones are so good. They move and make sound.
Body exhibition, be ready before you go in. Nice exhibition, but a bit mental.
Cons:
We went there in weekend, too many people and we had to queue. There was a cafe inside the venue, but also too many people and the drinks are a bit expensive.
