I always stay at Club Quarters, which is about a five or six block walk from the Convention Center. It's an old hotel that has been restored, and prices are not as high as some of the listed hotels. The rooms are a little small, but I always enjoy my stay there, and you are not there much anyway. They have a car that will take you to the Center in the morning and in the evening. Taxis are readily available for only $6.00 for as many as can get in the car, going to any where in the city.
