The Ambassador Hotel has a free parking lot behind it. You can ignore any numbers you might see in each parking stall and park any where in the lot. Also, across the street and kitty-corner to the hotel, there is a big parking lot for the restaurant Cafe do Brasil - we often park there instead and never have any problems.
