Join a Disney forum. There are many great ones- one that I have used to get tips is
The DIS Discussion Forums - DISboards.com - Powered by vBulletin there are MANY great tips for saving money there and you can ask questions about planning your days.
travel "helps" in general...
We have a vacation savings account. $20 from each (2 a month) of my DH's pay checks is directly deposited into that vacation account. We have never changed that amount and it's nice, because vacation costs don't take a huge blow to the finances when you purchase your vacation.
There are great vacation discounts out there if you spend the time to find them. Disney world online is a great place to book your Disney vacation, because they have the most up to date sales listed AND, in a package deal- it's much cheaper.
The Disney Dinning plan is very well worth the money! The one time we went there with out one (several years ago) we spent (ON AVERAGE) $40 per day on food PER ADULT!!! And now prices have even gone up.
As far as parks go- everyone has their "favorite"... and ours is DEFINATELY NOT Epcot (WITH KIDS!!!). Yes, it is a great park. DON'T get me wrong!!! BUT Animal Kingdom is by FAR MUCH MUCH MUCH MUCH better for families with children. It is our second fav. park because of how much they can do there. We find that going to Epcot my girls get "craby" very quickly, because they spend more time waiting around while DH or I goes on a ride. They do like Soarin' and the living seas pavilion- but after that they're ready to leave the park!
Our 3rd fav. park is MGM (now Hollywood Studios)...with Playhouse Disney, Little Mermaid, Beauty and the Beast, and many other shows and a few rides. If you're looking for the "kids rides" experiance and the not so much running to the next show and sitting for the show, then running to the next show and sitting- then the best places are definately Magic Kingdom and Animal kingdom, IMO
Money saving tips for your vacation...well there are MANY on discussion boards. The big money saver for us this year (other than our trip being paid for as a gift from DH's consulting work, which is a HUGE thing!!) is that we actually bought our "Disney attire" before we are going there. Disney store and online has MANY great deals going on throughout the year to buy t-shirts, sweatshirts and things. Every year we've gone there we've always let each of the girls pick out a sweatshirt, T-shirt and a nice Toy. The sweatshirts there range from $25-$40 and T-shirts $15-$25...We bought them each their sweatshirts before Christmas for $9.99 on sale and they are GREAT quality from the Disney Store- their t-shirts from the disney store were $6.99. BIG money saver!
As far as eatting there goes. If you decide not to get the dinning plan...portion sizes are usually quite large at most of the sit down restaurants- DH and I usually split a meal, then DH usually eats what ever the girls don't want from their kids meals.
If a "quick service" kids meal includes a "collector box" ask to get it with out the collector box and you'll save anywhere from $1.50 to $2.00 per kids meal.
With no dinning plan...eat your large meal for lunch. Prices run cheaper and you still get plenty of food! When you're on the dinning plan, eat your sit down meals for dinner- you get a little more food and get your $$$ worth...
Your resort hotel has a "gift shop" area that not only sells Disney items, but a few food items as well. When we are not on the dinning plan, we usually bring a toaster with us, buy bread from the "gift shop" and make peanut butter and Jelly on toast for breakfast. I also pack a box or two of cereal and buy milk at the gift shop each morning.
We will be on dinning plan this trip, which means that we definately do not need to eat breakfast in our hotel room, and we don't need to bring many snacks with.
