Honestly, I agree with the poster who said she feels annoyed. My husband in currently on active duty in the military, and when we can, we enjoy taking advantage of the deals to vacation WITH our family or friends (which is the intention of the promo and why the service member has to be with you).
I think anyone who tries to figure out a way around that, say, by having the active duty member activate the tickets and then hand them off without going with you, should be ashamed. The promo is a way to honor those who SERVE this country and protect our freedoms, not to save you a buck!
Until you have walked a mile in a military member or spouse's shoes, you probably cannot understand why it is offensive. My husband (and our friends) miss out on so many things--birthdays, holidays, anniversaries, school events, births, etc. They risk their life, their limbs, their buddies. Right now, my husband is very far away, and he will miss the next year with our kids. What Disney offers gives many servicemembers an opportunity to plan a vacation with their family when they are home. Please don't cheat to get a deal you are not entitled to--you didn't earn it, and you run the risk of ruining deals like this in the future for those who do earn it.
