Slot reservation System

Hi

I have created a WordPress site for my local woodworker club and we would like to add a calendar to allow members to book time in the shop. We can have up to 10 people at any given time during our operating hours.

Does anyone have a recommendation on a plugin (preferably free, but not necessary) that will allow members to pick hourly slots until the maximum number of slots is gone for that hour (10)?

Thank you for your help!
