Guys! Hotel business is not non-profit! Be hard and taff and ask for your upgrade! That is the way it works!

Hotels, in particular BW hotels, play dumb when the honored diamond member wants to get something for free. Be sharp and don't move from your position. It's your right to get an upgrade.

PS: Recently I got to hear that they only need to "upgrade me to the best room in the category booked", i.e. to a "better view" room. The hotel insisted that the Italian BW hotline instructed them (it was an Italian hotel). Nada! Ask for your rights!
