Can I set a maximum length of a package?

Example, 14 days maximum booking.

Not at this stage.

Currently our nomad members are able to add extra days from their base package.  A member that books one of your 14 day packages can add extra days, using the same per-day rate, to increase their booking length.

 If your room isn't available due to other bookings, or availability restrictions, then these extra days will be prevented from being added into a new booking.

But right now we don't face the ability to prevent this extra days, or from restricting to some other booking length, to be added into Packages.
