After the 2010 point reallocation, I look for split-stays!
We usually stay for 5 nights. I look to do our first two nights in a studio and we add a dining plan (usually the DxDDP) which will cover our meals for 3 days. That way, we don't need to order groceries. Then, we do a 1BR for the last 3 days without a dining plan. We eat at either CS places or eat some simple meals that we've packed (mac n cheese, spaghetti, etc) in our room. We do our laundry at that point and then we can go home with clean clothes.
I have so far done 3 split stays. The first one was 1 night in a value studio followed by 4 nights in a value 1BR at AKV. The second one was with my parents. We started in 2 studios for 2 nights at AKV-Jambo and then moved to a 2BR standard at Kidani. Both stays worked out just fine since our luggage never really left the property.
Most recently, in October 2011, I did my first split-stay between 2 different resorts. It was just my DSiL and I so there was not a lot of luggage involved. We started in a LV studio at BLT and then moved to a std 1BR at BWV. We scheduled our moving day to be our day at Epcot. We checked out of BLT and gave our luggage to bell services. Then, we went to Epcot, rode Soarin' and Test Track and then went to BWV to check in. By mid-afternoon, our text came that our room was ready. When we were done at Epcot, we went to the BWV, grabbed our luggage from bell services and headed up to our room.
I think in the future, I will definitely schedule our switch day to be a park day. That way, I don't have to worry about being "homeless" since we will be in the park anyways. For our next split stay, I'm hoping for a studio at BWV and a LV 1BR at BLT
