There are a couple dozen hotels located near our con hotel and convention center. Unfortunately, this is downtown Buffalo, so they are all rather expensive ($250 to $400 per night).
You can find out more about hotel room availability by checking travel websites such as Travelocity.com. Also, there is a better than even chance that you will find apartments to rent near the convention center.
Budget-minded travelers would be wise to either check out Hostels.com (some hostels do have private rooms), or plan on staying in another part of Buffalo and commute to the con via Metro. You can find out more about local transit options on the Getting Around Buffalo page.
Here is a map of Buffalo, centered on the con hotel. Note that the convention center is to the southwest of the con hotel.
