My family & I will be in B.A. from Jun 13-17 and 19-21, 2008. We are staying at the Marriott Plaza in BA. In Igauzu Falls area we will be at the Sheraton. We have never been to BA before so don't know much except what I have read on FT. I am planning to email the Marriott and Sheraton a few days before we arrive to beg them for upgrades!
