Just had guests to stay this weekend. They used four towels between two of them, and as we don't have a tumble dryer I now have four towels plus a set of bed linen hanging up to dry in the house.
Would it be unreasonable to ask future guests to bring their own towels (assuming they are driving and not travelling by public transport in which case I appreciate they might not want to carry too much with them).
Love having guests to stay, hate all the washing!
