Sorry...I posted in a hurry earlier. P&G (ie. Procter and Gamble, who have their offices in Emporium Tower) have a low corporate rate at the Emporium Suites...all you need is someone from P&G to make the reservation for you. They don't ask for any proof that you work in P&G and you can check in and settle the bill by yourself.
Alternatively, if you are staying for more than a few nights, you can negotiate with the sales department at Emporium Suites who will usually agree to a lower rate.
