@Pauline728 You didnt state whether you have washer and dryer or not. If you do, then the best thing is for the guests to use it. Otherwise D will be ok for them depending on how much they have to pay.
You can also list the a, b, c, d like that for them with different pricing for them to decide. Hope this helps!
@Gifty5 Mistakes are only human, but it's your willingness to help others that makes you amazing! What would you recommend @Pauline728 now that we know it's about turnover? 😃
