We do it all the time! It's fun to look forward to the new resort mid-stay. It's a way to try new places w/o abandoning favorites. Most of the time, it's a split between 2 resorts, but we've done triple splits twice. We plan our parks based on where we're staying often. I'm never losing time. They move your luggage (we moved our own prior to them doing that for us and it was still OK w/ a car), we never unpack anyway, we just go from the resort, to the parks and then to the new resort after that. Just as we would if we were returning to the original resort. I'm the one that does the check-in so the DH and kids go have fun as I take care of that business and we're happy clams. It's really a GREAT way to satisfy curiosity and add some zest to your stay.
