As far as thw weigh in and such TBH it may be off limits to the public...This is a big fight and there just may not be enough room to accomidate everyone....My suggestion is get there early as possible...no less then 3 hours if you want to get any type of decent view that may not even be enough time.....

Places not to miss in Vegas?....There are so many almost impossible where to start where to end and not miss 20 inbetween...presonally I woud make sure I went to

Hard Rock- Happening palce all the time, great atmosphere, great entertainment, a lot of celeb's
Hard Rock Cafe LAS VEGAS - HOME

Planet Hollywood- It speaks for itself really...But I mean for more then just the fact it is hosting the event..the place is hopping 24/7
Welcome to Planet Hollywood..

Ceaser's Palace, Pussycat Doll Lounge, The Palms, I could go on all day but those are my fave's and Planet Hollywood can keep you busy for a day alone
