Infinity Kids Sports & Learning Center

If you’ve got kids bouncing off the walls during one of Seaside’s many gray, drizzly stretches, this place is genuinely worth knowing about. The gymnastics and ninja classes are the main draw, and the coaches here actually seem to care — parents regularly mention how patient they are, especially with kids who take a little longer to warm up. Skill-building is taken seriously without being intimidating, which is a hard balance to get right. It pulls double duty as a birthday party spot too, so that’s one less rainy-weekend headache to solve.
