I wish we had a school like this by us! lol. When my son went to 3yr old preschool, all I looked for was the most toys and fun, thinking he would be happier, and he was happy, however he didnt really learn as much as I had hoped and was actually distracted a lot of the times by all the toys around him. This year we looked for a little more academic based preschool with fun elements, and great teachers! The teachers can make all the difference in my opinion, and I strongly suggest meeting the actual teacher of the class if at all possible.
Most of the preschools around me have way too many toys in my opinion. I agree with Sandy, sometimes they introduce things in to show the kids how to use it or introduce it when it ties in to the particular theme of the week or whatever. I think a little more organization and thought goes into this type of teaching/learning and I think the kids truly benefit.
Kids will learn and have fun just about anywhere. My friend sends her child to montessori and tells me they have no toys at all there. Just learning/development type things. Some of the things they have the kids do (learn) are to polish silverware, and wash dishes, and the kids love it! lol.
