No way, they are actually asking, would you do something that makes you uncomfortable so that this relative whom you don’t know very well can be more comfortable. I mean, we could all chip in and get him a hotel but then that would require something from us. We want you to take this on alone. Many people think that we should do unreasonable things for “family”. Unreasonable for anyone is still unreasonable. They should never have put OP in that position. Asking for an unreasonable favor is their bad. OP saying no is reasonable. Why can’t this guy stay in a hotel or the airport like other travelers do all the time?
