Having a guitar out that is easily excessible is very helpful. I grab my electric guitar and play unplugged all of the time. When I'm at home, throughout the day I may find 5 or 10 minute bits of time where I can grab my guitar and run through some things. When I am trying to really nail a lick, or firm up a song in muscle memory, I'll run through that stuff. Other times I'll just play whatever I feel inspired to play at the moment. Time with the guitar is time with the guitar.

When I play my guitar unplugged and my wife is in the room it annoys her. It's loud enough that I can't do that while she is watching TV. When I was single, I'd practice sitting in front of the TV all of the time...running through stuff trying to get it into muscle memory.
