It's really something you have to do the math on for your situation. If you're going to spend more than 10 days in Disney in a calendar year going to the parks every day then yes I would consider it worth it. For us we love that we get Tables in Wonderland, the memory maker included, the discounts on merchandise and special events is great too. But we go about 2-3 times a year for at least 5 days so when you price it out for us it makes a lot of sense. There are different ways to factor your breakeven point but if you're going purely on number of day yes it's 10-14 days a year is the break even point.
First time AP in a long time! We live about 2 hours away and it's so worth it! We first got a non discounted package with room and tickets and free dining. We were able to upgrade those tickets and pay for our annual passes. So many trips for the price of one. We go at least for 2 days a month.
