Overnight visits from company of any age find it helpful to have a series of night lights available from their bedroom to the bathroom, and even more night lights within those areas. Plug them in and tell your company that they are free to use them if they so choose. Parents of very young children as well as elderly visitors are especially appreciative of this extra "welcome to our home" touch. When your company has departed, collect all the night lights and house together in a plastic zip lock bag ready for the next visit.
