Personally I did not bring my 5 and coming 3 yo there as I was told by my friends that it is a small place with a ball pool, a small train that goes in a small circle, visit pororo's home. For that price and limited to 2 hrs, I hesitated to bring my kiddos.
Instead, if u want more fun, u might try " my little giant" http://the-js-arena.blogspot.sg/2016/09/my-little-giant-bigbox-indoor-playground.html?m=1. My friend brought her 3 yo and had so much fun. There are vehicles, train rides and other kiddy rides other than playground. It is unlimited playtime.
Hope it helps.
