If you tell your kids that every night a volcano erupts with fire, smoke, and lava right in front of their hotel, they won't believe you until they see it for themselves. Head outside the main entrance Sunday-Thursday evening just before 7 p.m. or 8 p.m. or Friday or Saturday just before 7 p.m., 8 p.m., or 9 p.m. Those the times when, whether permitting, you can see this incredible man-made spectacle during the winter. The times are an hour later during the warmer months. The volcano used to erupt every half hour from dusk to midnight, but as of July, 2015, the hotel cut back the viewing times to save costs. Sadly, this is just one example of the growing trend of Las Vegas casino hotels to cut down on free entertainment. The free tram between the Mirage and Treasure Island still exists, but the free pirate show that used to draw big crowds of all ages to the TI nightly is now a part of Las Vegas history.
