Quality of Accommodation - What does this mean? If someone stays in a site owned static caravan, for example, is the person is rating the caravan itself? Or the whole site, which would surely fall under 'Overall'. if someone was staying in a tent, what would they then be rating?

Maybe a little message shown to the user when they are reviewing to remind them what they are actually scoring for that particular section.

Also, if a site does not advertise to offer a WiFi connection, then a rating should not be allowed to be given, a N/A rating would seem fairer.
