Can I set a minimum hire length?

Yes. Go to Pricing → Pricing Rules and add a rule of type Minimum days, then enter the minimum number of nights.

You can apply it however you need:

• across your whole fleet, or scoped to a specific vehicle, vehicle group, category or location;
• and optionally to a date window — for example a 5-night minimum over the Christmas peak, and normal lengths the rest of the year.

Once it's set, the booking page enforces it automatically — a customer simply can't book a shorter stay.
