2959 did get permission to setup a venue wide hotspot last year (hopefully this year as well). To do that though we had a lot of restrictions and we had a network engineer manning it to make sure the signals didn't interfere with each other. So you might get permission provided you can bring $20,000 worth of equipment and a certified network engineer.
And even then the equipment was overwhelmed and was only so so. If we get the opportunity again this year we are bringing more antennas.
