(The secret, invite those kids! I was a nanny and a teacher for years so I invited all of my families I had worked with, and it was SO much fun! They kept people of all ages excited and dancing. And we had NO meltdowns ever. And by "we," I mean the kids. So many people leave them out, and then wonder why the dance floor only gets 20 people or so for four or five songs!
The other secret, choose music that is widely known, not just those special songs that mean alot to you and your husband. They are special, for sure, but no one else knows them or wants to dance to them! We did alot of iconic big band music, ones that got you singing along as you were dancing, think Frank Sinatra, The Beach Boys, Louis Armstrong.....and apple bottom jeans, lol!)
