Trying to decide between MGM and Cosmo for a long weekend in December (Sat-Tues). I have made reservations at both - Executive Queen suite at MGM and Queen Terrace Studio at Cosmo - both at nice rates. I just learned that Pacquiao is fighting that Saturday at MGM. How nuts will that make the property? Bad enough to influence my decision? I assume it will make self parking tough but what else will be affected?
