I'd like to add that the breakfast buffet at Mandalay Bay is one of the best I've had.
And as far as shows go, I enjoyed "Mystere" far more than "O". Why? While "O" is indeed a great show, it is all about the presentation and the arena; "Mystere" (at least to me) was the more traditional Cirque Du Soleli show with a "human circus/unbelievable body control" element.
