How big is your place, is it a small apartment? A split level duplex with 4 guest bedrooms on a different floor? Are you being asked to house them (IE provide a place for them to sleep) or host them (have supper on the table for them every day too)? I have to assume your cousin, even if you are not close, is not an idiot and has a fairly good reason for asking you. However, as someone else pointed out, you clearly dont want to do it, as evidenced by your little gripe about being used as a “hotel”. just say no. If you arent comfortable saying no, say no anyways, blame it on your spouse.
