Keystone Montessori Sandpiper Curriculum

Hi there -- I know I can go in for a tour and ask lots of questions, but wanted to get some insight first from recent parents.

My husband and I are looking for a daycare for our daughter (currently 12mo.) starting this fall. She's been in a nanny share since 5 months. I realized that by September she'll be old enough for Keystone Montessori, and since we have the nanny share until we choose to cancel, we have some flexibility to wait for a spot to open up. However, I'm not sure how I feel about a Montessori classroom for a 1.5yo. Does Keystone provide opportunities for unstructured play for kids in the toddler classroom, as part of their schedule? Are their expectations age-appropriate?
