This is mostly for @crcr-ray since this is his first, but this is a helpful reminder of things you'll need.
Computer. Laptop or desktop, doesn't matter. Don't be shy here. Most people bring their entire setup. Dual monitors, everything.
Plug strip.
Pillow & blanket. I'm always hot, but they keep that place cool at night. Depending on how well we work, we might actually get to nap so a pillow is a good idea.
