I used to have access to a large set of hotel review data. The median score on Booking was 8.1 (if you filter for business travelers it's in the 7s, but I'm not sure if that's available in the UI). This is partly because the scale is actually from 2.5-10, not 1-10 or 0-10 as you might expect. The rest is probably just because people don't evenly distribute ratings and tend to favor the top and bottom of the scale.
