I got a chance to try both the Hilton and Sheraton. Spent the week at the Hilton and then had to head back after UA and AA flights were cancelled out of GRU due to crew shortages from the volcano eruption. When I returned, the Hilton was sold out so I moved over the Sheraton. It's a definite step down from the Hilton. The club up on the pool level is a hoot though, my brazilian friend took pity on me missing a flight home and took me up there for some amusement value. There are plenty of hip places in Sao Paulo, but the club is very much stuck in the 80's.
