I would just like to know so I can buy enough cake and have enough favors. And if the majority left are "NO" then I would want to invite DDs other friends.
I would update the invitation to include "please RSVP by date" with "date" being the day before you need to buy favors, hopefully a week ahead of the party. Then set the reminder to go out a day or two before that
