As the owner you can let whomever you want use your points - you just book the reservation w/
DVC for them.
You can call to do so, or you can log in to the DVC member site and under the booking tab, book what/when your son wants to go, put his name as the lead guest & friend’s name as second guest.
Give him the reservation number you’ll get and tell him to link it in his
MDE (my Disney experience) account.
If he doesn’t have an MDE account he needs to create one as should his friend, which they can do via the WDW site. He can do everything else from MDE like customizing MBs, linking credit card, attaching tickets, etc..
If he wants a dinning plan you’ll need to add that for him by calling member services and I think DME as well if he’s flying in.
Remind him to buy his ticket before 60 days out so he can take advantage of those 60 day FPs, which he’ll need if he wants to ride FOP or the new slinky roller coaster
