Hi there Pete,
Welcome to planDisney and thank you so much for your question! How exciting that you'll be at the Disneyland Resort just a little over a week - are you counting down the days?
Currently, each Guests needs a valid
theme park ticket and
theme park reservation for each day they plan to enter the parks. Therefore, if you're planning on visiting over the course of two days then you would need a ticket for each day (it sounds like you all are using 1-day tickets for this) and each member of your party needs a theme park reservation for each day they plan to visit.
My preferred method of keeping track of all this when I'm the one planning the trip is to use the
My Plans hub on the Disneyland Resort website. It's an all-in-one place to make and manage all the different reservations associated with your upcoming trips - including theme park reservations.
If your reservations are already all set up then you should see them in the bottom half of the page. If not, there is a button in the top half of the page that will walk you through the process!
Thanks again for your question, Pete! I hope you have a fantastic visit to the Happiest Place on Earth later this month.
Have a Magical Day,
Greg
