easyReservations function

I need to specify the service in the order for 40 persons (including children under 6 years and up to 12 years). Order of this type if you recruit 40 people then only the position will close. If I buy the full version of the easyReservations plug-in there are such settings?

Yes, try out the demo.
Regards

How i can try the demo?
