I think a waldorf type kindergarten or preschool would have more outdoor time and almost no formal learning. Singing, movement, crafts (using real materials like wool and wood), puppet plays, stories, quiet rest, helping to make snacks or lunch. Children do learn a lot, but it is introduced in a subtle and rich way.
The slow path to academics has worked out brilliantly for my daughter (49 this year, ouch!) and also for both of my grandchildren, a 16 year old girl and an almost 13 year old boy. They are both smart, interested, involved and enjoy learning. Total bookworms, despite not learning how to read until 2nd grade.
So I think there is a difference between a waldorf setting and a regular preschool, but it might not be so obvious unless someone was carefully observing.
