I attended a Belair class and we placed a node in the parking lot on top of the instructors vehicle about 150' from the corner of the hotel. We had usable signal inside the hotel's atrium which was on the other side of the living space.
Here is a link to their design. http://www.belairnetworks.com/solutions/hospitality.cfm
I would be happy to elaborate if necessary or provide a Belair resource in your area. I do not work for Belair, just know their product very well.
