Mirage Resort and Casino’s famous Volcano show will not be as frequent as they once were. Since 1989 the show has been every 30 minutes starting at dusk and going until midnight. But now the Mirage has decided that there was too much other things going on to look at and the crowds were not what they use to be so why keep that schedule up for a small audience. The new schedule will allow for two or three shows instead of 8 or 10.
