Dont buy your ticket online coz its cheaper when you buy it there on the ticket counter. I'm not sure how come they are offering 2 days tour while you can finish all the rides and enjoy everything in 1 day so think about it before signing up. Try visiting after lunch around 2PM coz aside from its less crowded you'll save money because food inside is expensive plus your kids will still have the energy to wait for the fireworks display which happens around 9PM. Also, more events happen in the afternoon like the afternoon parade and around 7PM is the night parade which is both awesome and you shoud'nt miss it. Less queue on rides as well in the afternoon.
