A combination of aggressive use of hotel points (eg I paid for 7 nights in Bali just now, about 100-150/night for huge suites with my girlfriend, and am doing 14 days in Bangkok starting 5 nov for free on the points I earned (due to promos, etc).) and work reimbursement. I'm also sort of homeless in that I don't pay rent. (Gf has condo).

A lot is work reimbursed (looks like about 200 nights in 2014 if things go well), plus Starwood points from work and personal Amex.
