Babies and amusement park

A friend of mine wants to plan a day to an amusement park in the summer. My baby will be here in 6 weeks so they’ll be around 2-4 months during June, July and August. Her child will be 6-9 months. I told her if me and my SO go, I will not be bringing the baby. Frankly I just don’t think six flags as an example is a good place for an infant. Am I crazy for thinking this? I just don’t think crowded, loud environments are good. Plus it will be hot. Has anyone does this? What are your thoughts ?
