Can you go in to observe the actual goings on? The theory of the school sounds great, but sometimes the practice just doesn't live up to it. Take a look at those 3-4 others who are older, that might tell you a lot.
When DS was a little older, he would deal with daycare by finding one other child who was his favorite, and all was well on the days that the favorite was attending and willing to play 'only' with my DS. Other days were just sad days for my DS. I was working and basically felt that there was no other choice at the time.
I think you will know more when you observe.
Best Wishes,
