Yes, I have similar experience from a few nurseries in the area, I am not convinced of waiting lists I must say. For one particular nursery which I was told was very popular we were offered a place on the opening day. My neghbour was furious when we told her as she had been on their waiting list for 8 months. In the end, we did not go with that nursery and lost our deposit but the place was not given to my neighbour but to someone else who attended the open day, as far as I know she is still waiting... It might matter what days you are looking for as I know some nurseries give you priority if you want Fridays or Mondays (which are sometimes less busy) and also priority might be given to people who are looking for more days. It is frustrating to say the least - I feel your pain.
