What about having snack outside? I used to do this a lot as my snacktime used to be 9am...I would pack it all up and they would either eat it at the park or in the back yard. I serve snack at 8:30 now, but that's because I serve lunch at 11 and if I serve snack too late, they are not hungry for lunch. What time do you serve lunch? Could you move that up a bit as well?
