I would definitely check online first to find out how much you can get the room for there. I could get rooms online for $80 on the hotel's website for booking more than 7 days in advance, and that was just on one room. When I went to book a block they told me they'd give me 10% off for booking 20 rooms and that it would be $80 with the 10% off. When I told them I could get it for that on my own online, they agreed to give me 10% off the online price. I've worked at hotels before, and they can always give you a lower rate. So just do your homework to find the lowest rate, even looking at comparable hotels and keep in mind that you are giving them alot of business without them having to do anything. So make them give you a good discount!
