As you can see by my signature, I've switched resorts a lot, and actually prefer it for a longer stay. We're going for almost two weeks this July and will be splitting our stay at the GF and BWV. When I stay for that long of a time, after a week, a hotel becomes stale and I need a new place to stay. I think 5 nights and 3 nights is a good split, because it will give you an opportunity to settle down at each place. Moving isn't all that difficult, since Disney will move your bags for you. Just pack up in the morning, call bell services and tell them you're transferring resorts and they'll take it from there. Go to the park of your choice that day, and arrive at your new resort around check-in time and you're all set. Check-in and your luggage should be waiting for you to be delivered to your room. We do move our luggage ourselves, since we have our car with us and have to drive over. Also, since we stay for such a long time, we use the moving day as a non-park day and just hang out at the new resort's pool while waiting for our room to be ready. To us, this is less stressful and very relaxing. We just arrive at the new resort all ready in pool attire (coverups of course) and check-in. After getting our id cards, it's off to the pool for relaxation. I'll call around noon or so at first, to see if our room is ready. After that I call approx every hour until I get our room number. I say go for it, you won't regret it!!
