Well, I went ahead an reserved a first night, after having made sure the hotel showed up for the next 13 night. I ended up having to split the reservation into 3 periods (for some reason the hotel wouldn't show up for any other time period combinations. But I did get the Downtown Marriott (on Market St.), which is the one I had hoped for, for a price of 48 per night (including all fees & taxes). When we informed previously at the hotel for their best rate for a period of 2 weeks, the manager couldn't do better than $109 per night. Needless to say we're pretty pleased. THanks for your help.
