As several people have already posted without SOME idea what your preferences are it is impossible to give an answer. Absolute elegance four seasons or the Mansion at MGM. Casino and elegance I would say wynn, Venetian Aria bellagio Cosmo caesars probably in that order. However there are a dozen criteria that change things, dining options? MGM is now a contender, great pool? Mandalay Bay is now in play. Best sports book options LVH can get in the mix. Etc etc etc
