For our trip coming up in November, we are trying to do the impossible. Only carry on with 3 kids and 2 adults. Plan? Well.... we just bought three new 20" suitcases, one for each kid (4, 6 & 8), I have a 24" and my dh will pack in a duffle. I will also bring the backpack for activities on the way down (direct flight 2.5 hours) and for "stuff" on the way home. We will pack a smaller duffle for the stuff the kids collect that won't fit in their suitcases on the return trip.
The kids will be wearing jeans/fleeces down, so their luggage will hold 5 days worth of shirts/shorts/another pair of jeans, etc...
I don't know if this will work or not, but it saves us 25 minutes in the BUF airport (print boarding passes out online the night before) and at least 30-45 minutes checking luggage at MCO. Oh, and we just call Fl. Tours when we land and head right out to A35 and immediately into the car instead of waiting for luggage and the car to drive around.
Somehow I think we won't have enough room on the return flight for all their "things" the kids buy!

Maybe this isn't the brightest idea out there!

Hmmmm... I've got some time to think about it...
Oh, one more thing... as we take more trips to WDW, we have found things that can stay home and great ways to pack things. I never leave home without cough medicine for the kids ($7.99 for a small bottle in AKL gift store

). But I will spend $12.00 on laundry so I don't have to check luggage!
