Because the crowds are spread throughout the day, it isn't as busy during spring break. However, today is the last day of spring break, so it may be busier than Mon-Thurs but Noon-3pm should be a good time to go.
I would recommend earlier in the day.
There should be enough arcade to go around, but the rink can be crowded at night. I believe there are times where it is kids only as well as boys vs girls and etc
