Hey there Jennifer,
Welcome to planDisney and thank you for your question! Today is the day that Magic Key passes go on sale! Here's hoping that you're getting ready to purchase yours.
It sounds like you're hoping to buy more than one
Magic Key and are hoping to be able to pay with a payment plan? I'm happy to share that, since you are a California resident, you will be able to view monthly payment options - but just make sure you're logged in to your MyDisney account!
As for purchasing multiple passes, in general you are able to purchase more than one Magic Key but they are subject to availability. As noted on the
Magic Key Buying Guide page, "The quantity of passes and pass types available for upgrade or purchase may be limited or unavailable from time to time or at any given time, and updates to pass availability will be displayed on the waiting room page."
In other words, I unfortunately can't guarantee a specific outcome here in terms of quantities of Magic Keys and/or what payment plan options might be available for you, but I would definitely encourage you to hop in the waiting room for the sale by 8:45 AM Pacific Time today and follow the prompts based on what's available.
Good luck in your purchase today, Jennifer, and thank you so much for your question! I hope you make so many wonderful new memories over the next year with your visits to the Happiest Place on Earth.
Have a Magical Day,
Greg
