i dont have anything to say about the upsells, but i prefer bb over dh, at the dh you see all the girls at once and have to pick in front of them all, where as bb they come one one at a time, also bb has a shower in every room, where as dh only has one room with a shower, and the other option is walking down a common hall...plus i think bb has much better looking girls! and its a little more discrete getting in and out.
