Hi,
Will the twins share a bed? I was just wondering whether you were going to have them share the bottom bunk and your older daughter have the top, or will your son be on his own and the girls together, or will one of them have the sofa bed? Disney make a big thing of saying that the bunks are only for kids of 6 and over, but if yours are ok in bunks there should be no problem, I think they only do it to cover themselves if something should happen, eg, a small child falling out of the top bunk during the night.
We have always found the cabins to be comfortable and well equiped, they come with dishwasher detergent, but only enough for about 2 loads, so depending on how long you are there you can ask for more, the same with toilet roll(my kids always seem to get through loads

).
What sort of time are you getting there? We always get there about 9am, and have always been able to check in and get a cabin and all our passes, even though check in isn't until about 3pm, I think they just feel sorry for the mad english people that drive through the night
On our first day we go to the huge Auchan hypermarket at the shopping centre just down the road from Disney and stock up with drinks, snacks and some extra breakfast or supper stuff, it saves a fortune if you don't have to pay Disney prices for food and drinks.
The breakfast at the cabins is collected from a little hut near to the area of cabins you are in, hope that makes sense, you get breads and pastries, juice and hot drink sachets, along with jam and chocolate spread and butter etc, which you take back to eat in your cabin. They tell you what time the hut will open and close and you decide when to collect it, one of use would fetch it whilst the rest carried on getting ready and then we would eat and go to the parks.
The shop at the DCR is expensive for food items, but sometimes has the odd souvenier that is different to the things in the parks, and don't forget that you can have any shopping you buy in the parks sent back to the shop for collection later on.
If there is anything specific you want to know, ask
