Hello Jelle,

Thank you for your interest in using Amelia for your business. I understand your concern regarding the scheduling for paintball activities and ensuring that the same field is not double-booked.

To address your issue:

1. Adult Paintball: Set the working hours for the "Indoor Arena" employee to be from 9am to 10pm, with services starting every 2 hours.
2. Kids Paintball: For the "Indoor Arena" employee, set specific working hours for weekends only, from 9am to 1pm. This way, the kids' time slots will be available only during these hours.

However, Amelia does not currently support blocking adult time slots automatically when kids' sessions are booked on the same field. This might require custom development or using an additional scheduling plugin that integrates with Amelia to handle complex booking rules.

One workaround could be to manually adjust the available time slots for adult paintball around the kids' sessions to avoid overlap.

If this solution does not meet your needs, I understand it might limit Amelia's usefulness for your business. If you have any further questions or need more detailed assistance, feel free to reach out.
