Since we travel from the West Coast, I gotta make it worth my time.

Perfect for us is between 10 and 21 days. Our last few have been 18 days - approx 3-4 days in Universal and the rest at Disney. By the time we look to packing up, we have REALLY relaxed! It's still hard to leave on the last day though . . .

The days we arrive / depart are generally dictated by airline seat sales.
