FYI, VA ID cards are tan in color and strongly-resemble the DoD Dependent ID Cards (usually on the card, there is some sort of "Disabled Veteran" language).
To answer Grammyof2's question:
- VA ID Card holders cannot take advantage of this offer -- the Disney Website specifially states this offer is for Active Duty, Guard/Reserve, and Retirees and their families (and Disney ticketing personnel know how to distinguish the blue retiree ID card from the tan VA card (as some 100% service-disabled veterans often refer to themselves as "retired", which can cause confusion in customer service-type functions).
- The only time the sponsor needs to be present is at the time the tickets are purchased/vouchers redeemed at the main ticket window -- from there, everyone can do pretty much what they want.
