I have something like a small school blackboard. Prior guest arrival I write something as "welcome to my city" on language where the guest comes (google translate works just fine). I also draw the symbol of the city or the country where they come from. For example, if guests arrive from Paris I draw the Eiffel Tower, if guests are from New Zealand kiwi bird draw:). Guests are really happy and impressed with the attention.
Try it and see:)!
