A good hack is staying away from Downtown Dallas, and on a DART rail line that stops at the St. Paul station. No traffic, no parking, lower hotel rates, and AirBnB available too. Do some research with a Google map. Also, you could travel hack a room with a credit card sign up and some points. IHG has good deals for Holiday Inn.
I get to drive 45min. in rush hour traffic and fight for parking each day as a local...yeah!!
