Ok I have a lot of tips. First off is using the dining plan to its fullest. When we get the dining play we always get the Deluxe. This gives us 3 meals per day and 2 snacks. With this in mind we use 2 meals for dinner and one for lunch, all sit down. Even with having to have our 3 year old DD on the plan last time we still saved an enormous amount of money. Granted I ordered more food than I normally would eat, and as a result my tips were more, but still in all we saved a good deal of money.
Also with the
DDP we would bring our deserts back to the room and have them for breakfast. We would use our snacks to get orange juice and other drinks to have during the day.
This takes a lot of planning to get it all correct and my DW always does a fantastic job getting everything organized and planned for this.
The next tip is if you are staying on property to visit the parks with the extra magic hours at night They are practically empty and wait times are non existent.
On the flip side, visit the parks the day after a park has EMH due to more people visit on that day just because there's more time.
Plan your fast passes. Some rides are worth going and getting a fast pass right away, others not so much. But one good thing about the fast passes is that even if it says it is good for 11-1, it is actually good any time AFTER 11. We have used fast passes that were good for 10am at 9pm.
If you want to do toy story mania, be at the park the moment it opens and race to get fast passes. Even if you don't plan on being there until later, send 1 person with all of your tickets to collect fast passes for this ride.
Last tip, be EXTRA friendly to EVERY castmember. You will be surprised what they give you for being nice. Asking CM's for stuff will not get you near as much stuff. True story - we were at a shop and the CM's behind the register were playing a new board game that came out. We started playing with them and had a blast for about 20 minutes. At the end of it the CM's gave us a bunch of pins (that they could give away) and some other stuff they were allowed to give out. It pays to be extra nice to the CMs.
