Registration/ticketing takes a long time if you are using coupon booklets. Took us more than 20 minutes as only 2 windows process these. These counters should start atleast 1 hour before the park does.
Note: upgrade to express tickets at the gate itself, doing so inside is costlier -- double the price.

Parking is adequate (Rs 100 per car).

Buffet at Imagicaa capital was not worth it. Food was tasteless. Outside food stalls serve good food but at a steep price. 500 ml water bottles cost Rs 60 each (Though there are a few places with water cooler where you can refill your bottles for free).

Please ask for the map at the gate itself. You probably won't get it if you don't ask for it. Makes your life much easier.

Rides are awesome: There is something for everyone. But as I said earlier , express tickets make a big difference. This a must for those who want to complete all/majority of the rides as the more popular rides can have a waiting of more than 40-45 min for ordinary ticket users. Make sure you carry an extra T shirt as some rides can make you quite wet.

Snow park is good. Mobiles are not allowed inside unless you pay 70 bucks each. The gum boots provided are rather thin and feet do get rather cold after 25-30 min. Make sure you're wearing long socks and jeans/trousers because they provide only jackets with hood and gloves there. You can purchase socks there in case you aren't wearing any.
