Hi Tiffany!
Welcome to planDisney, and thank you for bringing this terrific Disneyland Resort vacation planning question to us hEAR! Oh boy! You arrive at Mickey's house tomorrow, Tiffany!!! I know you must be so excited.
There are currently two ways of purchasing
Genie+ for your Disneyland Resort theme park days: either by buying a ticket-that-includes Genie+ everyday of your whole trip,
or, by adding the service to your already purchased tickets
after you've entered the theme parks each day. I'm really sorry that the vacation package you purchased through Costco didn't have the already-included option. I'm going to chalk that up to Genie+ being introduced less than a month ago and that maybe there are plans to sell a bigger bundle in the future, but that certain travel companies didn't want to sell the service before or too close to the launch.
I actually like how your Disney days are going to play out better than pre-book option. While you
will have to purchase Genie+ every day for four individual days vs. just the one time, and only after your party has entered your first theme park each day which gives a little more push to be there at rope drop the whole trip, the each-day addition actually gives you the option to sort of test the service out on day one to see if you even want to purchase it again for the next three days vs. making that commitment up front.
I do hope that you enjoy using Genie+, Tiffany. Be sure to update the
Disneyland Mobile App on all of your devices today, and don't forget that this add-on service also includes any
Disney PhotoPass landmark and attraction photos from each day of purchase too!
Tiffany thank you again for stopping by planDisney, and We'll See You Real Soon!
