Other than APs and careful point planning I've gotten very good with making our trips affordable
Have you canceled trips?
Are you cutting back on trips? NO. Added more, but then life did a 180 on us
Are you doing things differently at home so you can still take your Disney vacations? Yes, focusing on our trips as the big entertainment of the year saving money by not doing as much 'other' entertainment (less movies, ballet, theater, boating etc)
Will your upcoming trips be different than they were in the past? How so? Yes, they'll be more relaxed as we know we'll be returning - which in turn means we don't mind spending more time at the resort and less in the parks (bigger savings there too)
My to-do list for trip savings:
$$$: Shop shop shop for airfare. If I have to commit to a higher price trip I make sure it's SW. Also, consider alternate transportation - Train (buy far enough out and you get the best deals) & Driving on your own (if able - I can't drive from MA to FL all on my own.)
$$: Eat in! The reason I fell in love the villas to start with was the kitchenette.
$$: Pack & check
an extra box with the food items we love from home. Having brand names and food we're familiar with will encourage the above.
$: buy rechargeable batteries/film/memory cards
AT HOME. All parks everywhere will whack you for these.
$: Use the
free water in the parks as someone else mentioned. The only issue here is I've found AK to fight back when I ask for ice/water - we just bring our own containers and refill.
$: Use A
livery service to bring us to/from the airport instead of Drive & Fly for the long trips, Use
Drive & Fly or the T station even for the shorter trips.
$: Use ME. If I need a
rental car - shop shop shop (I'm in the process of trying to figure out how to get the best rental deal now- tips are appreciated!)
$: Give the pets a vacation. I hate seeing pets caged up at kennels, why pay tons of $$ for their misery when you can
ask a friend/relative to stay with them? I offer my spa services

to them and their pets in return.
