First, thought I'd start with my questions: we too have a 1 day MYW just to qualify as a package, but are buying the military promotion tickets. Can I apply the MYW ticket to the value of the purchase of the military promo ticket if I buy it at the gate? & if not, what the heck do I do with our 3 1 day MYW tickets? We have tickets already. Can I apply the adult ticket to a child's ticket for my son when he turns 3 if it's never been used & so locked to me, or is that against the rules?
If you bought the basic 1 day ticket, you likely paid full gate price for the ticket, so you shouldn't have to use it first. But, what if you didn't? Be superstitious, use it first, then upgrade during a break later in the day!
On the 4+3, I got a tad obsessed! Basically the "+3 free" promotion doesn't save you anything on tickets unless you add the "No Expire" option in the package. Whether you do 4+3=7 or 5+3=8... 7+3=10, you'll only save ~$10. However, the "3 free" also applies to the "No Expire" option when you book it in the package. That's where you can save $$$.
What you DON'T want to do is book "+3" tickets in the package & then add the "No Expire" at the gate.
Ex:
The current gate price for a 7 day MYW NE is: $367.58.
The current gate price for a 10 day MYW NE is: $479.25.
So through the package you'll pay $367.58 for 7 days, get 10, & save $111.
Once you use 10 day ticket once, you lock in the extra $111.67 in value.
An adult first time AP is $499.49, or $20 more than the ticket.
So you can (at least in theory) use the promo to upgrade to an AP for a total of $387.58, or 22% off the regular price. All while complying with the rules.

. I just booked the deal with one day base tickets because we considered getting APs since we want to go back in December and then again in June 2010 
. So I figured APs were the way to go
