This past January I couldn't decide between WL and AKL, so did a split stay and loved it. It was like having two vacations in one. In a week we went from the Pacific Northwest to an African savanna. In May, I did a solo trip and was a little concerned about doing a split stay. I stayed two nights at POP. rented DVC points for BWV for five nights, then added two more nights at POP. It was great and very easy! I wanted to do another split stay in a few weeks for our Sept trip, but my D-I-L didn't want to and besides with the free dining it was easier and cheaper to stay in one place. I'm already afraid I'm going to get bored after a few days. I'm taking my mom for her first ever trip in Dec and am doing another split stay at POFQ and CSR. Can't wait!
FYI: Just in case you didn't know WDW makes switching resorts very easy. Just call bell services the morning you're ready to leave. They'll come get your bags and transport them to your new resort. Go check into the new resort, get your room key, go to the park, and when you return that night call bell services for your bags. (At a value resort the bags will already be waiting in your room for you.)
