Water Kingdom is the best water park in India in my experience .I visited Mumbai with my family in year 2010 the water park was real fun.We don't have time for saying so we planed for same day to essel world and water kingdom both,but i like water kingdom the most.There slides are very quality and water was so clean that if we drop a coin we can easily find it.I must say the slides very real adventurous and dangerous to for newbies.Especially the black closed one with tube which is very dangerous and risky because of darkness in side the slide.The tickets prices are little bit higher than other parks,but you will never feel that your money was wasted.I must say i f you visit Mumbai,please visit water kingdom for sure you will definitely love and enjoy it.
