As far as admission goes, that sounds good. Assuming hoppers, if you'll be in the parks more than 11 days during a 366 day period, an AP is the cheapest route! There are also a lot of other great discounts not on resort rooms that make an AP valuable.
If you want a discount on an AP, buy a regular ticket from a discount broker (or non-expiration base ticket under the 4/3 deal), use it once, and then upgrade! That can help defer costs and make the AP a better deal too.
