Just been to Adlabs Imagica yesterday on 15.10.2013, it was an amazing experience. Kids (3 years old and 10 year old) too enjoyed it a lot. Though there could be some more rides for toddlers which I heard from their staff that are planned to be introduced.
The weather is very hot so do not forget to carry caps. They sell the caps at RS 250/- each.
To avoid hot sun one can plan to see the indoor attractions like I for India, Mr India, 360 degree show, space Ali Baba, Rajasaurous etc in the afternoon and enjoy outdoor rides after 4.30 pm.
The staff is very very polite. The attractions and rides are of world class but the safety jackets they provide during the boat rides are bad, they stink. One more improvement area is the food.... We went to have out lunch at around 3.30pm ... all the restaurants were running out of stock with very few options available.
The italian restaurant was serving pre-prepared pasta which was looking stale... Chinese veg fried rice and dumplings were horrible in taste. Better idea is to halt at Macdonalds or any other restaurant have breakfast and only then enter the theme park.
Overall nice and enjoyable.
