If your wife wants to shop, set her up at Lai Lai. The Hilton did not seem quite as nice but both are in the downtown shopping area. Hilton is a little closer in. Can walk to everything. I found Grand Hyatt to be a sumptuous hotel but very far from the action. Since it is your collective money paying for cabs, location should be a big factor. There are some fantastic bakeries near the department stores also - a real surprise to me.
