What is the best day/time for younger kids to go enjoy the rides? (7 and 5, my 7 year old really loves coasters)

To get the full effect of it i would go later in tue day when the lights are on

Go early in the day and stay hydrated, or go evenings after 7 it looks much cooler with LIGHTS than day..

Loke Joe said, go early, then when it gets hot you can stay inside the arcade area.

Might be best to go early...bring sunscreen!
