If they're playing at the Bradley Center (where the bucks play) or the US Cellular center, I'd recommend Aloft hotel. Mrs.00 and I stayed there for a weekend trip back when little00 was still in a stroller. Walking distance to a lot of stuff in that area...Usinger's sausage (well, that's for me, I suppose), a couple of breweries, the bronze fonz, etc. Was a nice hotel, although they don't have on site parking, they have off site.
playing at Marquette's volleyball arena, it looks like.
