I was there in May for a private retreat. I saw plenty of humans. Jenny herself stopped by every day to chat and check out our projects. It was their 2nd week of being open after the lockdowns ended and they were SUPER busy, but every single employee was friendly and helpful.
BTW, there is a new retreat center that has opened up in Hamilton, check out the pictures here:

The space is huge, everything is on one level (no stairs!), they even have a separate private room for your bus driver if you hire a non-quilter. It's a 5-minute car ride to the shops.
