As seen on the plot, we don't tend to win big deals with thousands of rooms (this includes group of hotels).
We see it in the zoomed-in graph that most of our customers are in the 0-200 room-range, and 0-2500€ price range. However, there's no clear cluster of won deals versus not-won deals - it's impossible to tell them apart.
Below we can see simple correlations between sources, deal owners, organisation type and even rooms/value.
None of them have a strong correlation with whether we strike a deal or not, it looks very random. In fact, number of rooms and deal value have one of the weakest correlations!
