You can try using my Worth It to Upgrade to AP? Spreadsheet. Try putting in just the one adult, then enter all of your estimated ticket type, park days, food, merch costs. Also select MM at the top.
It should give you an idea of whether the AP will be worth it.
With a 7 day PH with MM and a bunch of TS that may have the added AP discount I suspect it will be worth it to you.
