What The Value Of The Ticket For My Daughter, Aged Two, At The Magic Kingdom?.?

Note that all the ticket say children over 3

Where Can I Buy One Day Ticket To Magic Kingdom? Also My Daughter Is Nearly 3 Will I Have Prove Her Age?

I will only be in Orlando for a short while and with a little one I don’t want to spend too much time in the parks as she will be too small for any of the rides. Thank you.
