I have been trying for those exact dates for months. I started my bidding really low and have gone up to $74 for a 4* and $72 for a 3.5*. (I am holding off on a 3* bid due to the possibility of getting the dreadful Millennium property). That weekend, there are three Cardinals home games, a Rams home game and two (probably cancelled) Blues home games, so any cheap rooms will be released at the last minute. The hockey teams stay at the Westin, so there will be a last minute cancellation of a huge block of rooms there if the lockout continues. I am using points as a backup plan, as several properties were still offering awards for that timeframe. Don't be tempted to take the HOTWIRE 3* at $117. You WILL get the Millennium, and they WILL put you in an old, dirty room in the basement. I've had several people at the front desk tell me outright that Hotwire/Priceline bids get the same block of terrible basement rooms. Since then, I give a huge tip to the desk clerk at check-in and they always "just happen to find me a room in the new tower".
