Another perspective (sorry it's so long):
I don't really like split stays and try to avoid them at all costs. For me, the idea of a split stay and trying out different resorts always sounds more attractive when I am still at home planning my vacation. Once I am at Disney, it is a big hassle and a time waster, in my opinion. Mostly because it is usually DGS and myself, no rental car, and relying on Disney to transport our luggage (which can take several hours - I made arrangements at POP to pick up my luggage at 9:30 am and move it to Poly. Luggage did not arrive until about 6:30 pm after much checking with bell services, which would not be so bad at all, but Disney insists guests be
IN THE ROOM to receive the luggage which can be a real time waster if there is any type of confusion on their end. They will only deliver luggage to an empty room with ME).
That said, sometimes I choose to split my stay. For our next trip, we are renting points for 4 days at SSR. We will stay in a value resort for the first night (to save money and be better rested for our first DVC day) and move to SSR the next day. I am also thinking of adding on 2 or 3 nights at the end of our stay, but will probably not want to add on at SSR, so might move again (remember, it sounds exciting when I am here at home) to yet a third resort.
I keep telling myself it will be so much fun to try 3 new resorts, but honestly, after aching feet and tired muscles of 5 days at the parks, I really just don't want the hassle. Oh, and the reason I don't go ahead and just add on days at SSR is because the resortaholic in me has me waitlisted at a second DVC for those 4 days, so not sure if I'll even be at SSR for the rental portion of the trip. Confused?
Last year, I moved to a new room within the same resort (CSR) and between the time I checked out of first room and personally dropped off my luggage with bell services, until the time my new room was ready, they misplaced my luggage and no one knew where it was. They even had me looking in the back to see if I coud find it. Nope it wasn't there. It wasn't a huge deal and I know it was just a mix up which all ended well, but it did waste another hour I could have been in the parks.
So I really don't like split stays and may regret this one, but gosh, while sitting in front of my computer at home out of the hot sun, I envision this smooth transition from one exciting new resort to another and that thought can be quite thrilling.

There is nothing quite like the moment you step into your Disney resort lobby for the very first time... or how about the first time the green light flashes after inserting your KTTW card and you are stepping into your new room for the first time.

I need help.
