This year, we're going much smaller for a few reasons... DS10s' football team went on a hot streak and made it all the way to the 5th grade Super Bowl. That extended the football season until the Saturday before Thanksgiving, 3 weeks longer than normal. So it killed my set up time. Plus, we were in WDW for Thanksgiving week and will be there for 11 days around Xmas/New Years, so we're only home for 3 weeks of the season this year. So for this year, I'll only have a few thousand lights outside. They will still dance to music I broadcast on FM radio, but it's a fraction of what I'd normally do. My "normal" set up is:
Roughly 40,000 lights outside. A mix of white, colored, multi-color as well as a mix of size...regular "mini", C7 and C9 (those are the large ones), etc..
About 1/3 of the lights dance in sequence to music played over FM radio (I do the programming myself)
Several blow ups...Santa, Mickey, etc...
About a half dozen wire frame figures....reindeer, a dog, etc...
A "scene" or two that I set up
10-15 artificial trees covered in lights
Bushes covered in lights
Etc....
Inside the house, we have:
About 500 lights (the mantle, staircase railing, etc...) If you count lights on the trees, it's several thousand total.
7-8 Christmas trees (3 real, the rest fake)
Christmas village
A crazy amount of "nik nacks" such as nutcrakers, figures, things you'd see at Michaels or Hobby Lobby
Basically, the inside of the house is as over the top as the outside
So yeah, we go just a bit nuts. For 2018, we plan to include RGB technology outside. Those are the lights that I can make change to any color I want, and can change any bulb to any color at any time...very much like TV.
