Depends if it's raining! We go there on rainy days and it's much more busier than normal. That said, even on a busy day there is so much to do the busy growds do not really effect the enjoyment for the kids.
There was about 30 on Sunday. Probably about the same on Saturdays
I'd say way more would be there in the afternoon than those that come in the morning. Its not bad in the morning.
