Do I have to pay for a parking pass at the cowboys stadium for the cowboys vs Texans preseason game if I am getting dropped off at the entrance of the stadium.

If you are dropped off you do not have to pay for parking.

I just recently seen where the game will be canceled.

no

Yes best to get drop off

Not sure about that game exactly since some of the proceeds are going to the Houston relief. But you usually have to and getting dropped off is your best bet if u can.
