My kids are older now, but their ages are 27, 19 and 14. We always split up in the morning and I would take the older kids on the big rides and DH would take the younger kids one the kiddie rides. We would meet up for lunch and then stay together the rest of the day. We did this at all the different parks we have been to over the years and it really worked out well for us. DH doesn't like thrill type rides while I love them so he was always happy to spend the morning in the small ride areas while the big kids and I rode the big rides.
