Whenever you visit that far (like coast to coast) you have to decide how much time you actually want to spend in that particular city and then add two days travel for time there and back. The flight their and back can be very long IMHO and I never include those days in the number of days I want to spend in any one place. For you guys from back East, it's definitely not a one/two nighter I would think.

I don't like a long flight only to turn around a day or two later and board another long flight. I need at least 3 days between.
