I spent time at the Sheraton for a very large conference this past year. Group rates for staying in the hotel were a good deal. Staying in the towers were very nice. The rooms are spacious and the views of downtown Dallas are wonderful. The conference itself was more than easily accommodated in the several large ballrooms in the convention center. I know they said they can accommodate upwards of 20,000 people if they have to! Also, the hotel connects to a neighboring hotel next door by way of skywalk, so if you have overflow there is more than enough room for everyone. Between the hotels in a large shopping center with a food court that has plenty of options. There also little souvenir shops for the out of town people. Overall, the facility was clean, well maintained, and the staff was friendly. My only cons are that the wi-fi in the rooms is not free and that parking can be an issue (either you pay a lot or you walk a long way to a cheap garage!)
