From day one I have had a small chalk board outside the room and I always write Welcom (guests name here)!
It never fails, I'll be chatting with the guests and one or the other of them will noticetheir name on the board and immediately stare smileing and going "look look, my name!" People love to see their name written when they don't expect it.
So, if a pair of people book and they tell me 'My husband & I..." I always ask what their husbands nam is.
Once though, I only wrote "WELCOME Sally & Sally's Husband!" The guests got just as big a kick out of that too. The husband was such a good sport, he called himself Sally's husband all weekend long.
