LOL! Me too! Guests should be thanking ME!
I don't get overly effusive with them at first to be honest. I never write Looking forward to meeting you! Because it really isn't true. Once they are booked, I send them a document which has everything they need to know about staying here plus says thank you, etc... And if I get to see them leave I always come and say goodbye and thanks for staying... But I don't overdo it!
To be honest, I don't treat any guests any differently. If they are coming for a honeymoon, they get fresh flowers in the room. If they aren't, they still get flowers. ( From the garden... Not ones I've bought. ) I cannot afford to get goodies for anyone. In the past when I have done this, left goodies, they were either not acknowledged or they were criticized (!) for not being BETTTER goodies!!! Seriously!!! That's all it takes for me to burn out on leaving goodies.
I have hosted other hosts and have always felt intimidated! Like they are sizing me up! Honestly hosting other hosts invites nit pickiness. And makes me nervous.
