Hi Onou,
I work in a mid sized hotel, but the property is split up among 27 buildings, and has chickenwire wrapped concrete walls. Keith's suggestion of the 7055 would be your best bet to ensure coverage in each room. Use the 7982 in your conference spaces, and depending on how busy the property gets the other common areas as well. AirMagnet is my suggestion for the SW to use. I haven't seen the Ruckus tool, but Ekahau also makes great planning tools. Get a decent laser tape measure and then a good map of the property with correct physical dimensions. Walk as much of the property as possible, then run your various scenarios. That's going to be the best way for you to truly get a good site survey.
