Monster Pumpkin Festival in the Strip

I know this is a bit out of season, but just curious to hear if anyone has attended the Monster Pumpkins Festival in the Strip. Does it get a good crowd? Is it too overwhelming to bring small kids? I know they have a good number of activities geared towards kids, but my young nephew gets pretty anxious in large crowds. I just found out he will be visiting that weekend (Oct. 17 & 18) and I am excited to start planning fun stuff to do with him. Thanks!
