The Bellagio Fountain Holiday song schedule has been updated to include holiday songs. The current rotation has a holiday song as every 3rd song. It makes the times easier to predict if you don’t have the schedule handy. The holiday songs play at 4:00pm, 5:30pm, 7:00pm, 7:45pm, 8:30pm, 9:15pm, 10:00pm, 10:45pm and 11:30pm during the week. They add 1:00pm and 2:30pm on holidays and weekends.
The schedule will change each week until January 3, 2022 when it reverts to the standard playlist. You can see the current schedule on my Bellagio Fountain Show Songs and Schedule 2021 page.
