WiFi hotspot for hotel

Hi, I have task for building network for a hotel I'm working for. The hotel has strong and thick walls with armature, which make signal looses very quickly. I'm considering for a ceiling-mount points, but from what I've read so far Ubiquiti are not so reliable or maybe depends on model. So I'm thinking to buy RB1100AHx2 - http://routerboard.com/RB1100AHx2 as WLAN controller or software on a PC - The Dude

and
these routers as a ceiling-mounted RB2011UAS-2HnD-IN http://reloadbg.com/product/395/

I don't know if these will be OK and reliable enough?
Thank you.
