PHOTOPASS!! this is a great feature, use it. Try the Disney Springs Photo Pass Studio, it's free and you get several photos with say 8 cool projected backdrops very fun.
You may need to ask but most of the time you can acquire a free AP Magnet for say your Car or Fridge.
Like other people have said pull it out everywhere on property whenever you purchase ANYTHING, not just Disney stores or restaurants Everywhere
lot's and lot's of places take it, to many to remember or list easier to just ask every time, easy 10-20% off.
Setup so you get email's, I am hoping I can get into Star Wars Land for a Preview like I did Pandora, we got an email with dates and times for the preview and QUICKLY signed up and boom planned a trip around the time we got. We were in Pandora for say 3 hours with like 500 people, went on Flight of passage 4 times in a row and the River ride 3 times, was perfect. I Am hoping we can get this for Star Wars. That lands will be impossibly busy when it opens.
When you enter a Park look for the AP Line, most times the line is shorter + everyone in line knows what to do so the line moves lots faster.
