Thanks for your replies. I received a call back from the Dallas Market Hall last night. The man said that rolling totebags were allowed. I am taking mine along with a shoulder tote. If they give me trouble, I will check the rolling tote and add goodies to it all day. They do not allow them in Houston, except with a doctors note, so I check mine. When my tote bag is too heavy, I go to pkg check and empty into the rolling tote. It is worth $1 to save my back. At the end of the day, I roll it out and back to the hotel or garage. My rolling tote folds flat and velcros, so getting it in is not a problem.
