I went with my 7-year nephew and niece and they both enjoyed it a lot! The attractions are different; very interesting and creative, compared to other theme parks. Definitely a must-go place when you have kids. When we went there, it was not that busy, so we could ride the attractions for couple times in a row without waiting for that long.
We took the coach bus from Singapore. The bus left from Singapore flyer in the morning and took us at Legoland and it dropped us back at Singapore Flyer in the evening. You have to buy the coach bus ticket at least 2-day in advance. They have a package ticket (coach bus + admission ticket to Legoland -check the Legoland Website for the coach information and where you can buy it). We bought the ticket online at Sistic (it costs 2 SGD more per ticket) but it was easier than to go to the ticket box especially if you do not live in Singapore. Then we picked up our ticket at the SISTIC authorised agent.More
