My guess has always been that DVD made a common mistake in the interest of saving money and pulled the existing wire to the new APs as opposed to re-inventing the infrastructure to a more suitable solution. More times than not, trying to retro networking is a bad idea. I've been doing it professionally for 35 years. It wouldn't be hard nor expensive to get it right. It's not free. We pay for it. I'd just as soon pay for something that works, as opposed to having to depend on my phone or a hotspot when I'm there and have to get 15 minutes of work done.
Most of the guest AP's are behind the TVs for Christ's sake. Interference at its best. LCD TV and a wall behind it. I won't get into the technicals of how WiFi signals move about, but suffice it to say that is pretty much the definition of worst case scenario. There ought to be Ubiquitis or Ciscos in the ceilings, but I digress.
I actually had a hotel employee, back in the days of the wired rooms, jokingly (I think.) tell me that I should relax. I was on vacation, when the LAN connection in the room didn't work. I nicely told her my clients didn't care if I Was on vacation, and that my work paid for my right to take one. They eventually moved us to another room.
Gone are the days when we could "escape" on vacation. Most of us have to be connected these days. It's part and parcel to our professional lives and livelihoods. And for many of us, phones and iPads don't cut it.
There needs to be an outcry from the membership to stop treating WiFi in the guest areas as a luxury item. It most certainly is not. Not anymore.
