Rich myself, GyroF16 & some 'tard named Pipes have stayed sev. X's @ a < 1yr. old HIX in Addison right off Belt Line Rd. & nearby are many other hotels but I'm UNC if your preferred props. are in that immediate area.
I'd recommend staying west of the Galleria area on Belt Line as there are a metric ass load of restaurants etc. in Addison that should cover any needs you have w/ out having to venture into the traffic etc. that the Galleria has to offer.
