I'm trying to maximize my return, while minimizing my amount of work spent. I have estimated my days out of the country, and it's over 600, but I've been with 4 different companies, and let's just say around 10 different cards. So, I don't want to do option 3.

I look at 2, and it asks my travel purpose. I would say this is close to 50% business, 50% vacation. What do you think these questiions mean? The choices are Biz, Visit friends, vacation, or other, and the selections range from never to mostly (and you can click all of them mostly, it's real intuitive, one would think mostly would = 1 choice.)

My guess is that if you click business, they will assume a coporate card, and disallow a large chunk. If you select visit friends, they might assume you do not incur a hotel charge, and have a reduced per diem, again just a guess...

ANy insight into the use here?
