My girlfriend and I went last year and had a great time. We did see Second City and a few bands live in the city to keep us sane after hearing female jazz vocalists played in every room. (If they weren't being featured when we entered, then someone would invariably request something). If you're not into that than make sure to visit KEF who kept changing things up.
Also be prepared for listener fatigue (I never experienced it before) and for megabuck systems to be somewhat disappointing without a dedicated, treated room. The omni-directional MBLs fared well though, as did the Vinni Rossi\Harbeth room (at like a 10th of the price) which utilized nearfield placement to amazing effect. And Spatial Audio did wonders too for even less, though the sweet spot was a bit too narrow for a couple.
