How much does an outdoor playground matter, for preschoolers? The preschool that has a good curriculum and convenient location that works for us doesn't have one, and also only serves catered food. Are these deal breakers?

For me, I think that while having a balance would be the most ideal, if you find the curriculum good, you can still consider the place. For outdoor play, you can bring your child out in the evenings or during weekends for some family fun. So I feel that it would not be a deal breaker. In terms of catered food, if it is of a good and healthy variety and prepared without using too much oil or seasoning, I think it should be fine too. Just my two cents!
