What's the downside to keeping the account but just not posting to it or checking your news feed? That's roughly what I do, and so can still use it for events and such. I also have it set to email me if my wife or my mom posts a picture. (My mom posts about once a month, and it's more often than not a picture of one of my kids... ;) ) Anyone else I care about (and only the people I really care about) I have on Instagram, which I check every day. But my Facebook feed I view approximately never.
