Wow... that is some stunning arrogance by those travelers. Thanks for the follow-up and glad that it worked out. Sounds like the host is stand-up, but has gotten taken advantage by some arrogant guests on a few occasions.
Regards
The good thing is the host can provide feedback against the guests who took advantage as a warning to other hosts about this couple. I'm proud that I have excellent feedback as a guest from all the hosts I've stayed with and hosts do read it before deciding on a guest.
