GWTW, you are absolutely right. My bad, I had wrong dates in mind and the timings is as you say, not advantageios at all.
DW also wrote me, and laid out which conferences and events Tyhee is looking at putting effort into, and it appears CH conflicts with other, better events. So I don't think Tyhee will have a booth at the cambridge house show in Vancouver, although they have not ruled it out yet.
Thanks for your vigilance! Reminds me of someone who has a real attention to detail.
