Thanks so much to Eee-va and MaiynaMouse for the great suggestions. I will definitely check in to the packages- I didn't even look at those as I thought it would be to pricey.
Great food suggestions. We don't drink much soda, and take a water bottle everywhere, always
Yeah, we do very light breakfasts as well, but I like to make sure we have at least one fruit to help keep things balanced

- well pack some so we don't have to search out groceries on precious mouse-time.
I think you are right- we can probably cut the food budget down a smudge. Can't miss the strawberry funnel cake though- we MUST share one of those beauties - way enough there for three
GRACIAS!
Do you have
AAA? I think parking is free at DL with AAA ( at least it use to be), and you could save on the Shuttle expense.
I see many families taking sandwiches into DL. When our kids were small that is what we did. We brought juice boxes, snacks, water and sandwiches into the park. When the kids were a little older we usually stayed at nicer accommodations which included full breakfast, but still came back to the hotel for lunch and had a cooler with lunch meats and all the fixings.
I remember on those tighter budget trips, I even packed fried chicken, mash potatoes, gravy or a casserole, salad, something I could reheated in the microwave. We used to bring paper plates, tablecloth, utensils, water, everything! I made it look nice and appealing! If we were lucky, we would only eat one CS not each day, but the entire trip, no water, no treats except one Mickey Ice Cream each) in the park!
Back then for the car trip down, I would pack a beautiful tablecloth and bring sandwiches, drinks, salads (I made), for a quick picnic at one of the rest stops! We would always remark how we had the best picnic and everyone was not eating as well as we were with fresh homemade food!
Our kids are in their late teens, but old habits are hard to break, they will only have one treat the entire stay (their own choice.)
One word of caution since you are on a tight budget, write a list and plan out everything you need to bring and what you are eating, so you do not forget anything!
When the kids were very small, we won 4 two day tickets to DL and they were about to expire, so we had to go. We did not have much money, we were counting the pennies ( if you know what I mean.) I found a cheap, clean motel and we made all our food to take with us! I did not make a list, and in the early morning ( 4:00AM) when we were packing the ice chest, I forgot some of the food!

We have two refrigerators and I forgot to look in the other one.
When we got to DL and it was time to have dinner, we had no dinner! I cried and cried! We had to split the first dinner into two dinners...not good! We really had no extra money to buy food, since we were stretching the budget already! It was the worst Disney vacation for me ever! It was no big deal for the kids, they do not remember, but one of the worst memories for me! Make a list and check it twice!

Good luck and have fun!
