I'll try to provide something semi-useful here -- maybe help the WoV people out a bit with some practical information. I don't know if anyone has posted elsewhere regarding the Mayweather/Pacquaio weekend in LV, but there were many reported issues around town.
First, many supposedly respectable venues, reportedly including a Buffalo Wild Wings and the Blondie's in the Planet Hollywood mall, offered seating and a meal with a fight broadcast for $200-$400 each. I do not know if these events were four-walled (outside promotions company leased the places for the night) or whether these were gaffes by the companies themselves, but they collected payment up front in the days before the fight, then announced hours before the fight that the events were canceled, and that you had to return to the venue to get your refunds. As you can imagine, these turned into mega-ripoffs, as people would then scramble to see the fights elsewhere, and would leave town Sunday without ever getting refunded. I do not know if MGM/Mandalay simply disallowed these properties from showing the fight or if it was a ripoff from Moment One. I was unaware this kind of promotion was this common, and the ensuing rip-off as prevalent as it was.
Also, evidently CET scheduled big drawings for 6 PM at Planet Hollywood and 11 PM at Caesars -- Saturday night!! People were astounded. You could not schedule a worse time -- and you had to be present to win with a one minute window -- on the most packed night of the year. Why would they want people who were gambling to leave their seats for drawings??
Add in the Pacquaio-injured scenario, and it was a bad night for the tourist in LV.
