I've flown carry-on only most of my life and I've done up to two week trips (business and personal) with only carry on luggage. I'm also not the type of person that just hangs out in my hotel room after work. Of course if you need to wear anything nicer than a polo shirt to work this may not be possible. 1. Wear your bulkiest shoes to the airport 2. Find pants that can be used for work and play (I like Kuhl Slax) 3. Plan on doing laundry (or paying someone to do laundry) on trips over a week. Make sure you bring clothes to wear on laundry day! 4. Don't bring crap you won't use, but it is ok to bring items that you don't necessarily need if as long as they add value to your trip. As an example, I always travel with my Olympus EM5.2 and two lenses.
