Congrats!! I'm still waiting to hear on the ticket draw -- they extended the notification date to Nov. 10th, so you are among the first to hear.
I entered for 4 tix for the June 29th game in Recife and the July 4th game in Fortaleza. I booked with miles into Recife as soon as plane tickets became available. Never saw anything below $1600 when I was looking. I booked refundable hotels for the night before and after each game (although they haven't actually charged anything yet).
