I am also Staying in September. This will be our 3rd in the past 5 years about this time of year. I also have kids the same age that we travel with (3, 6, and 8).
Magic Express is great. Quick, easy to use, and very convenient. Especially with kids in tow. Definately use it!
Can't speak to the resort...haven't been there.
In 2005, we stayed at Saratoga Springs and had groceries shipped to the resort. This was perfect because a Disney vacation club resort with a full kitchen and dining room. We were on the dining plan (and also had an infant), so the groceries mostly consisted of breakfast items, snacks, and baby items.
I would NOT recommend it for your trip however, since the room is not equiped with a fridge or other kitchen ammenities. An alternative, is to pack your breakfast items and snacks and bring them with you in a duffel bag or extra luggage case. Then you'll have the extra luggage to pack your souveniers for the return flight home.
I did this on my last trip at the PO-FQ and it worked great. I put the kids favorite cereal in a large zip lock (takes less room) and bought the milk from the resort store. I brought instant oatmeals (that can be made with hot water from the in-room coffee pot)...stuff like that. It will save you $$ too.
I recommed the park hopper. Especially if you are on the dining plan. It allows you to be more flexible with your dining reservations.
I am working on my dining reservations now too (just booked the trip today). I recommend making them asap. I've found it works well if you work with the extra magic hours. Plan your days in the parks with the extra hours and book your meal around the park you will be visiting. For example....if we are going to MK, we will most likely plan a character breakfast either in the park itself or one of the MK resorts - Contemporary (Chef Mickey's). Then for dinner we will eat in Crystal Palace or go to Grand Floridian, since it's so close in location. This way you are not spending your all your time on transportation.
With the kids, I've found it much easier to have well-planned itinerary. Be flexible, but mapping out your days makes it much easier with the kids...for my family anyway:animwink:
A couple of dining recommendations:
Disney Studios - Book the Fantasmic Dinner Package
Epcot - Dine in Canada
Remember if your kids are picky eaters, you can check out the menus online. I have one that only eats plain pasta and grilled cheese. It has saved us a lot of time and frustration knowing which counter service and restaurants serve these items.
Good Luck...planning is a lot of fun! It builds up the excitement.
Enjoy your trip.
