My wife and I are flying out of BRU next April and I got sticker-shock when I saw the going rates of hotels. We ended up using Marrriott Rewards points to stay at a Category 3 Courtyard, which was asking 399€ a night. Crazy.
I'm certain the rate at Marriott's Champs-Elysees was lower than that when we stayed there a couple years ago on points, and that's a much nicer property. Oh, well, supply and demand, I guess.
