First time for NYE was 2000 and the last time was 2012, the year before we moved to SWF, 13 years to be exact, we stayed at Venetian for the first four then MB for the rest fo them, it's a zoo, but it's crazy fun, plan on being totally worn out for a few days..............always keep your wallet in your front pocket, take a coat/jacket if you're going outside, have fun and take pics.
