While staying deluxe is nice, its is also costly. I agree with some of the PP that renting points for a DVC might be the way to go .
DH and I have stayed deluxe a few times, but only for super special occasions, honeymoon, anniversaries, a special celebration and only for a long weekend. While really nice and enjoyable. We prefer to stay in a moderate, or a family suite (AOA), depending on who is with us. The cost factor is something I just can't ignore. Saving a couple of hundred dollars a day or more... for us is the way to go. For instance - AKL is 583.00 a night, standard room - which means looking at the parking lot or roof line it goes up in price from there if you want a savanna view, AOA family suite is 412.00 for a lot more space, 2 bathrooms, and 2 TV's which is nice if you have kiddos with you and some privacy, or POR which is 250.00 standard view, so if you are coming for a 6 or 7 night stay that's a lot of money that could be spend on other things, like a dessert party, or BBB or Pirates makeover for the kids, a fancy meal for mom and dad... or adding PH to the tickets. For DH and I we use the resort room to sleep and shower. We prefer to have the money to enjoy some extras when dinning, or shopping.
If flying use DME to and from the airport.
You can use Uber to get around if you want a run to the grocery store, Wal-Mart or one of the outlet malls, When my friends come they always arrive really early like around 8 or 9, they stow there luggage at bag check and grab Uber and head to the outlet mall at the end of I-drive, do some shopping, and there is a Publix within walking distance right outside of the mall and they grab some stuff for the room, and Uber back, hit the pool and they early to bed this works for them.
Grocery delivery - for breakfast items, water and snacks
You might get lucky and free dinning might be offered when you are visiting so keep this is mind, and run the numbers and keep running them.
Think outside of the box for meals...
Sharing is allowed at most restaurants, except of course at buffets, and kids 3 and under can eat off of your plate. As a suggestion you might want to spend some time checking out the menus to see what is available and easily sharable.
We love to do appetizers for meals, we would get a couple of appetizers sometimes we would get one or two side salads to go along with the appetizers if we were really hungry. There are some really big appetizer and most are really plentiful. Then hit somewhere later on for dessert.
We like to eat around the world showcase in Epcot, sharing everything as we went around.
Having breakfast in room is a great way to save money and time in the mornings, and actually get some food into your kiddos.
Bring snacks and easy breakfast items with you for the room.
We always share snacks, and this way we can try more.
