Hi David, welcome to planDisney!
You have a great question, and I'm happy to give you my personal opinion and experience!
If you are planning to manage the
theme park tickets and the
Disney Genie+ service for your family, then it's perfectly acceptable to leave them all linked to your
Disneyland Resort account. However, it sounds like your wife and kids may want to access their own tickets and Genie+ on their own mobile devices. If that's the case, then I highly recommend everyone create their own Disneyland Resort account, and link everyone's tickets to their own account. This will link everyone together as a group and will allow you all to book Genie+ attractions for each other, or split up separately if you want to do your own thing.
To do this, first, have everyone download the
Disneyland Mobile App and create their own accounts. Then, to link everyone together as a group, everyone will need to add all the party member's tickets to their own Disneyland Mobile App. You can do this by opening up the Disneyland Mobile App, clicking the three horizontal lines in the bottom right-hand corner, selecting "Tickets and Passes", and then selecting "Link Tickets & Passes". This will allow you to scan the barcode of each ticket that you would like to link.

See ya real soon!
