Sounds like you and your DH are in a similar situation as me and mine.
We are heading to WDW this August and will be going back in Oct. for my borthday!
We are going to purchase 2 APs.
Our perspective is this: the AP pays for itself if you visit WDW more than 11 days a year (I think that is right). So we are going for 7 days this time around, 3 in October and plan on maybe a March and definitely a next summer trip. So we are taking the savings on park admission tickets. We did not take advtange of the AP room discount, because we added the dining plan and you cannot "stack discounts" as I have learned on this website. (We enjoy the dining plan and consider it a big enough savings that we selected that route instead of utilizing AP room rates).
All of that being said, we were able to get a nice discount on our room for August anyway using a public discount code, saving us $332.
We also know that AP room rates are not guaranteed, so we are looking at the AP pass as a way to save money on park admissing and get discounts at some Downtown Disney shops.
I hope that helps and was not too hard to figure out! It makes sense to me as I type it!
