I'm not sure if my guests are much of dancers. Our guest list is smaller, with a make-up of: age 5-10 (8), age 10-20 (2), age 20-30 (8), 30-40 (4), 40-80 (21). I am deciding between music options (dj, live band, or iDJ). I don't know if I should invest so much in music if guests are not much of dancers. What else can I do to get them moving or at least be entertained?
