Hey @Robin4 ,
It's always the few who spoil it for the many, isn't it?
My first late-night / last-minute IB experience was just after the IB feature came out... I think I'd set it to 11pm, and we'd just returned to Chicago and started hosting here.
Guy said he was playing a set at a local bar and would come over after he was done, 2-3am. OK why not? The fact that he was local etc never crossed my wee little mind.
About 6am I fell asleep ... about 9am, I got a note from him that he was in a local hospital but might still need the room when he got out ...
Guy then proceeded to submit his hospital documentation to me (not ABB) for a refund. Come to tell, I later found that the guy had a song about shopping local ERs for narcotics, and appeared to have done just that for evening entertainment.
The vast majority of my last-minute bookings have been fine, but a large part have been entitled, and a small but notable section, far worse.
The first line of defense, alas, is a cutoff at 11, 10, 9, ... 8pm etc to filter out and let others deal. In this case, I don't know how the listing got set to midnight, so might suggest that everyone check their settings to make sure no listings have defaulted over to a situation they don't want.
Cheers, Ken
