Nothing spells summer fun like a midway ride. Make sure the kids have the required height for a specific ride before entering a waiting line. (And don't try to fluff their hair to look taller, I tried and it ended up in tears.)
I recommend one adult per age group when visiting an amusement centre
(going with another family can help). Otherwise, older siblings get bored
to tears in the kiddie rides, and young ones have to wait while their older
siblings enjoy big kids rides.
