Sorry, can't help but just a quick thought:
I'm in my 40s and don't do facebook but I do know that many, many people can view your page, is this correct?
If so, do you really want everyone to know the exact dates you will not be home and away on vacation?
Have a great trip!
Well you can limit who sees what on your facebook page, so if I wanted only very close friends to see it I could set it as such. Also, my house won't be left unattended during the trip, some family members are staying home. So I'm not worried. Appreciate the concern, though!
