Sometime RV Resort WiFi .......... You fill in the blank!

We've talked about it before, and here we are again.  Mobile internet connectivity.  

Currently I'm in Casa Grande Arizona.  I'm staying at one of the parks I'll be working with this week.  I decided to sign up for a week with Airbeam for WiFi in the park.  Unfortunately, the service doesn't work well at all.  Actually, the word I'd use is "unusable."
