LA 2028 logistics — tickets etc.

We want to go to the LA Olympics with our kids. No flights needed. Realistically, when do we need to think about booking accommodations and tickets? I’m getting emails about reserving luxury suites and the like—we’re not that demographic. Ballpark budget for tickets? I have no idea where to even begin with planning; have just always wanted to go and since we live in California, would love to make it happen.
