The cleanliness does matter, especially depending on the age of your son. I pulled my son out of Gymboree when he was smaller because we kept going around and around with sickness and 2 stomach viruses in a month at 15 months was my final straw. He started part-time preschool last year and we had a lot of colds (more than usual) and a few sore throats which of course got passed on the the new baby brother but I knew to expect that because of the close proximity to 9 other kids. The stomach viruses etc however didn't show up this time so I think that shows as part of the cleanliness factor of the preschool when it comes to their toys and table surfaces etc. They also each had their own pencil/crayon boxes and scissors so I think there was less chance of cross contamination. I'd definitely question their sanitizing/cleaning practices where you're sending him.
