I stayed at 3 this past May. AKL, BC and CSR. The AKL and BC were only 3 day stays each. Basically, I never unpacked. Just took out the necessities. The final move to CSR was for 6 nocs and also the last move so I unpacked everything there.
I like seeing the different resorts. A few years ago I stayed at FOUR of them. It takes me about an hour the night before moving to get everything together and another 30 minutes the day I'm switching. It's a fun thing to do but I've done most of my multi-resorts when I've been down there alone. The one time I moved when I was with DH, it took longer.
With a long stay, like the one you're going to have, it should make for a nice change in scenery.
Good Luck!
