As promised, I got some pictures of the YC room maps when I was there earlier this month. I sent the BIG images to Dee via email so that she can format them in whatever way she likes for the thread info. But in the meantime, here are some smaller versions. The 'First Floor', etc. labels were added by me, otherwise these are the images used by the front desk at the hotel.
I posted BC maps when we were there in 2016, and I glanced at the ones at the YC front desk... they looked the same. This isn't surprising, since when we stayed in 2016, they had just finished the BC room renovations. Clearly these YC maps (which say November 2017) are post-YC room renovations.
