Bought 3 tickets at full price for the "any day" pass and our 4 year old was to get in free for the pre-k pass. The day we arrived, we were told the pre-k period had ended a few weeks ago and we would have to pay another $50 for him to get in, or we could wait another 2 weeks for the new pre-k registration period to open back up, and would be able to bring him in for free then. What is the point in having a small period of time where you do not let the pre-k in free? And really, $50 for a 4 year old who can't ride the majority of the rides anyway. We purchased "any day" passes so we could go ANY DAY. If they are going to let 3-5 year olds in free, it should be year round, not just a random few weeks where they do not allow them in free, and that just happens to be one of the days where we decided to use our ANY DAY passes.
