We have almost always done split stays. Our stays have been between 7 and 10 days. We rent a car so we usually transport the luggage ourselves, but we've also had bell services move our luggage and that worked out, too (though we didn't get our luggage at resort #2 until late afternoon). We love to try different resorts, and usually do one monorail and one Epcot resort. Packing is not such a big deal for us. Usually we bring 3 suitcases (one for me and DH, one small one each for my 2 DDs). We pack the night before our move (after the girls have gone to bed). We generally empty one of the small suitcases out and pack it with our dirty laundry before moving to resort #2--that piece of luggage is never opened again. Never a problem. Minimum 3 nights at each resort--we tried a 3-2-3 once, and the two nights felt like we didn't have enough time to enjoy the resort. We like split stays--it feels like we get two vacations in one, which my girls LOVE.
