For all intents I think the fight is made, I went to PAC/Erik3 alone and had a blast, bought ticket last minute of eBay, sat and partied with Brits I got tick from. Played a lot of poker that trip. 70-30 me and my brother going, hold off on buying a ticket, could sit with us at fight. If you don't mind know it all canadians.
Expedia for flights and hotels have always worked out great. Monte Carlo hotel reasonable and close to both manbay and MGM. All websites will announce ticket info, usually the Saturday after fight is announced, don't ask me why tickets just always go on sale on sat. Prices likely to be in the $400-$600 range down to 50-100. Try to stay on short side of ring, not on press side for sure. If there is a fight at the pearl at hard rock on Friday, go , it's a neat venue for boxing. Vegas is a great time, be it with friends or wife. Juan said Jan 20, look for a press conference, I'm sure it'll be Morales.
If they go on sale at MGM or Mandalay bay box office that is always the best place to go. It's a big fight but probably won't sell out, so ticketmaster will work. Unfortunatly stubhub etc get a lot of the good seats and are sometimes worth the extra cash. Both of these arenas are set up awesome but watch out for ring post lower seats especially at mandbay. Seen Erik/Pac1 at MGM, was unbelievable, you'll have a blast. Don't worry about staying near these hotels cause getting there is half the fun
