First and foremost, if you're coming to this place from the freeway, ignore the signs. It takes forever to get there from there. Get off the freeway at Speedway, and just head west following the signs. Plus you get to go through Tucson Mountain Park which is great (I'll review that some other time).
The internet works pretty good here, I get LTE with ATT. It doesn't cost anything so that's also a plus.
