Kid Tips

Toddlers & Pre-K: Normally this age set is too young for most amusement parks, but Six Flags offers a slew of gentle, cartoon-themed trains, slides, and carousels for the littlest ones.

Pre-Teens & Teens: For an additional $20, the "flash pass" allows kids to reserve their place in line without waiting in it, while the device lets you know when to queue up.

Planning Notes

• Start early. It's a 30-mile drive from downtown St. Louis via highway, which is quick, but you'll need to make an early start to avoid the lines that build throughout the day.
• Pack for it. If you're planning on taking advantage of both amusement and water parks, take a change of clothes and leave the gear in a rental locker.
• Make a plan. Hit the big rides early, and eat before noon or after 2 p.m. to avoid long waits. End the day splashing at the water park for best results.
