I said other - because it was really both.
It would have made $$ sense on face value for us to have just bought MYW tickets for our 7-day stay in April. However, after crunching the numbers, I saw that we would save some money on our rooms (and the other softer discounts, like DDE, tour discounts, World of Disney, etc.) and come out just slightly ahead if we both bought AP's. Plus, we didn't have to stress about "should we use up a full day if it's only going to be a half day in the parks", etc.
Plus, by taking the leap and buying AP's, we now have a great incentive to see the parks at Christmas, which we have never done, and can also take another trip in the spring before they expire. I still consider my purchase a "win", but I don't know if I would have necessarily leapt to that conclusion without the other included discounts.
