What's wrong with people, an $800 voucher is pretty nice to go on another flight and if the flight is the next day, you could easily get a hotel paid for as well as food vouchers.
Your incorrect. Many times they do not want to put you in a hotel or anything for putting you out like that if taking the flight voucher. I had a united incident a few years back in Houston, Tx where I got bumped and was the last flight out. They gave me a voucher but refused to give me anything to cover food, hotel, toothbrush, etc (all was on the plane).
