Game Lab
Game Lab is one of the few offerings I found with camps for partial day on public school parent teacher conferences (11/2/2023). There are other half-day options already up for the course of the year- I just am not tracking those on my site yet!
They have outdoor only game camps if you have kids who prefer to expend their energy outside.
