In my experience there have been problems for a while with sleep/wake if you have external monitors. I'm running 10.12 (work computer, no option for 10.13 yet), and I have three monitors connected to my MBP. I had to adopt a ritual about disconnecting the first screen, then lifting the lid a bit to activate the internal display, then disconnect the other two monitors, then close the lid. Otherwise more often than not when I woke my computer up next it would not have a usable desktop -- the dock would be on a nonexistent screen and could not be found. I got pretty used to using spotlight to load terminal and blind type 'sudo reboot'.
