Yes wifi, at the time of writing I'm getting 100 mbps down and 30 mbps up. I get full bars of cell service inside too but data seems pretty slow (at least for 4g), it's still good in case you need to make a call or text unlike some other places I've been. I didn't see anywhere to charge my phone so bring a battery if you have one, just in case.
YES, they do.
