At least two last-minute bids were received yesterday for Atlantic City's Revel casino, which closed this month, setting up an auction to challenge an agreed sale to a Florida developer, Reuters reported yesterday. Bidding on the two-year-old casino, which cost $2.4 billion to build, will start at $94 million. Revel's owner obtained a stalking-horse cash bid of $90 million from Glenn Straub, a Florida developer.
