Travel packages for the World Cup

My wife and I are thinking of attending the World Cup in Brazil in person in 2014. I’m guessing that to get hotel rooms and game tickets and so forth, the most practical approach is to get some kind of travel package… but we’d also want some amount of time to wander off on our own and travel to the amazon or something.

Anyone have any recommendations for travel companies to work with, or words of wisdom from having traveled to previous WCs?
(I’m definitely interested in seeing the US games, not sure if that means there’s no point in doing anything until after the pools are drawn, etc.)
thanks

Seems like there were lots of reports of scams at the last World Cup and at the London Olympics. I’d be very careful in who you buy from and how you pay. Might also look into trip/travel insurance.

Otherwise, sounds like an awesome trip.
