So they basically got away with it. $600k when they're charging $250-$1K per wireless account? Yeah...that's fair.
Personal experience:
I was a vendor at a conference in this exact hotel in 2013. Internet access was ridiculously expensive...per account which they prohibited sharing between devices of course. Handy when you're trying to present and sell technical services...and your hotspot doesn't work. Many vendors complained about how their hotspots weren't working, quite a few sucked it up and paid the extortion fee. Now I guess we know why. What I want to know is ... where are the refunds? Where are the damages being paid back? My conference was fairly small (this hotel is beyond enormous mind you) and there still had to be 100+ vendors. We were one of ... I don't know ... 5-10 conferences that weekend?
At a bare minimum the FCC should find them equal to all the WiFi access fees they collected while this system was in place. Would some have paid anyhow? Yes. This is meant to punitive after all.
Oh...and don't let me get started on how they *required* you to "rent" carpet for your booth 10'x10' booth (starting at several hundred dollars) and pay for power connections - another several hundred dollars for the lowest ~300w 110v connection. Then there were fees to receive fedex boxes, fees to store them until you got them, fees to deliver them to you, etc. Want to rent a TV for your display? They quoted something like 6 grand for two 42" TVs with speakers. Yah huh. The vendor that got that quote laughed at them, went to costco and bought two TVs for ~$1500, then raffled them off.
