Thanks to everyone for the tips. I think that the 10-day rule might not be too much of a problem for the Asia/Pacific trips from East Coast N.A., since our scheduled business often takes up 3 days on-site, we can easily add some other useful business activities in the region, and can add some business activities to the European stopover. And I'm interested in adding a little holiday time to the long-haul trips that I do. We probably won't use RTWs all the time, but might do so for a couple of trips per year.
