Every half-hour during the day and every 15 minutes at night the lake in front of Bellagio explodes with color, light, and water! We visited Vegas in November 2005, and this was my favorite thing we did. The first show I saw made me cry; it was so beautiful. The music was a mix between classical and Southwestern; it sounded like it was made just for that show. We stayed and watched about 10 different shows, and they were all wonderful. We never saw a repeat the whole time we watched the shows. The water is pushed up in the air to impossible heights and flows to the music. The shows last as long as the song and then start up again to the next song a few minutes later. The music was suited to all genres. There was Broadway, classical, contemporary, and even a country song or two. My best suggestion is to go at night; you truly get the full effect of the lights that time of day. If it is chilly, go in to the patisserie inside Bellagio and grab a hot chocolate. Find yourself a place down front and enjoy the show. If I could only do one thing in Vegas, it would be this.
