To get that 11 month priority!
But also, we don't mind split stays. We also often fly in late at night, and I confess I hate paying for a 1BR or 2BR when we arrive at 11pm at night, so often I'll book a studio for the first 1, sometimes 2, nights, and then transfer to the larger room after. Disney makes it very easy to transfer, as they will move your luggage/belongings/owners locker to the new resort for you. This gives us a chance to spend some time at two different resorts.
But our different resorts also allow us to be strategic -- stay at CCV & BRV or PVB when doing the Magic Kingdom, RIV for Epcot and Hollywood Studios, AKV for Animal Kingdom. So depending on the "purpose" of our trip, we may want to stay in different areas to make it easier to get to/from the parks we are interested in visiting.
And then of course at 7 months, we can combine things if we want to stay at a resort we don't own (for example, I like to stay at BCV when I take my BFF to Disney for a girls getaway weekend, but I don't own there), or for when we are doing big trips and want to splurge on something like a CCV Cabin or a Grand Villa.
