Gatlinburg Request

This is bizarre, but I was hoping someone could fulfill this request. My family is weird, and my brother, husband, and sister-in-law and I made up a couple and sent Christmas cards to my parents from this fictional family. Last year my coworker mentioned they were taking a trip to Gatlinburg and they said they could mail the letter from there. So guess what? The fictional couple moved to Gatlinburg. I accidentally named the wife after one character from The Birdcage, and I just can’t let this fictional family disappear. We would like for this couple to get weirder and weirder each year, but would like to continue mailing the letters from Gatlinburg. Is there anyone willing to share their address or PO Box, so I can have them mail the letter from Gatlinburg?
