Does anybody know how far the xfinity hotspot wifi extends throughout the parking lots? We are planning to bring a TV and streaming ESPN (and horse racing)and having a kick ass tailgate before the game. We usually park in the wholesale food distributor (jetro?) parking lot but not sure if wifi extends to that lot. Has anyone used it to stream tv outside the stadium? Never done it outside the stadiums so anyone with knowledge, ideas or insight into how well this will work is much appreciated.
