A lot of travel sites work this way, in order to give people a range of options on location, price, and rating. Hotels, hostels, bed-and-breakfasts, sometimes even the occasional private residence.
Wait a while until the hotel listings go up on the BronyCon site, and I think you'll do better. Based on this past summer's rates, a five-night stay might cost you between $150 and $200 if you come in as part of a group of four or more. Almost all of the hotels are only a few minutes' walk from the BCC, and the light rail line that runs from Penn Station will put you within very easy reach of them.
