I did it once and it really wasn't too much of a hassle. I went to WDW about 3-4 days before DH got there, and stayed solo about 3 days after he left. So for me it was studio, 1 BR, then studio again. But in all honesty, even though it was OK, I didn't love that his vacation worked out to be right in the middle of my trip, and encouraged him (actually both of us) to plan differently in the future.
