Hello, Risa! Welcome to planDisney! Before we get to your question, let me say thank you for your service on behalf of all of us here at planDisney.
I'm excited to hear you will be taking advantage of the
Disney Military Promotional Tickets. My family gets excited every year when the newest promotion is announced. We are actually stationed in San Diego currently, and there are plenty of MWR ticket offices between the many different Navy and Marine bases from here to Anaheim for you to get your tickets. Unfortunately, you cannot make theme park ticket reservations until you have your tickets. This is because reservations are booked and attached to each ticket number. This does make it difficult in your situation if you are not purchasing your tickets until you arrive in California.
I suggest you keep an eye on the
Theme Park Reservation Availability Calendar and get to the ticket office as soon as you can. Once you have your tickets, you will want to link each ticket to your Disney account on your
Disneyland app. Once the tickets are linked, you will then be able to go in and make your theme park ticket reservations. Keep in mind the reservation system is fluid and changes minute-by-minute. If a date becomes unavailable, keep checking. I have had success stalking the calendar the night before and seeing availability finally open up.
Risa, thanks again for stopping by. I hope you are able to get your tickets and reservations easily and have the most magical time at Disneyland Resort. See you real soon!
Carrie
