LovesDumbo, I think that's a great idea to go down a few days early with DD to "setup". I'm sure you can handle the luggage and grocery shopping, how about DH with the 4 and 2 year old

?
An adult friend goes with us. My DS is the toughest and he LOVES my friend and is so good for her and he'll be nearly 5. So they'd have her bag (she packs light) a carryon, stroller and 2 kids. I would do a town car for DD & I, a town car for them and then all van or limo back to airport. I was thinking I just can't do the May trip so I should just start planning the Oct trip. I would really like to do more than the 7 nights we did last time but I can't ask my friend to go for much longer. So thats what got what thinking of going down with DD ahead of the others. We can do tea at GF and all the thrill rides she loves. Then we'll still have a great trip with the others. It sounds perfect to me but I don't know what DH will think.
I'm with you. I can't imagine a 26 hour ride in a camper with 14 people. I think camping at Disney would be fun but not worth they money compared to other options. I've stayed at the cabins and really liked them but the other hotels have much better transportation options. I don't think I'd do it again without a golf cart so you might as well stay elsewhere.
