Again I would say no need to do advance booking while you start travel from India... You get enough tickets available in online portals there with discounts... Evening light show is a must and is amazingly beautiful.... try jungle safari with kids , they will definitely enjoy... Personal advice  don't buy anything from here... its too costly.. same stuff available at airport and other places in the city and a much discounted rate... I purchased t shirts for my kid but not worth the money... If you have visited Universal studio you might not find visiting this place worth the money and effort... restaurants inside are very very costly.. try bakeries instead...
