My advice for obtaining 70,000 points in the Festival Dance is to move from partner to partner as quickly as possible, also hitting the three claps each partner swap gives you in order to add time to your clock. Once you are able to hit the Situation Command to bring everyone into the circle, hit it quickly and then use the time it gives you to raise your multiplier before finishing the Command. If you move quickly enough, you should be able to do the SC twice, which is where most of your points will come from. Move quickly, keep your multiplier up, and hit the SC twice, and you should break 70,000.
