Does anyone know if Disneyland offers Military Discount?
Yes they do offer Military Discounts. What you need to do is go to your base MWR office. The discount varies from about 8% to 30% depending on the time of year. If you are a Southern California Resident you may do better right now with the 2fer ticket since you are going in March. What you do is pay the regular price for a 1 Day Admission($66 adults/$56 kids(3-9). You can then go to one of the parks on one day, then return on another day(within 30 days) and go to the other park for free.
