I believe the per diem rate at Omni is $48/day internationally. That may or may not be adequate for your needs overseas. Depends on how well you want to eat, but in places like Japan that amount won't go very far.
So....I did some sim work at DEN recently for a gov contractor. I checked my hotel rate at checkout. It was pretty pricy so I inquired with the front desk. I was told that I was seeing the government rate and that the gov rate always includes breakfast. Hmmmm, that breakfast is costing tax payers about $35 per day at this hotel, in addition to the room charge. I will already be receiving the daily gov per diem rate which is twice what any civilian airline pays. Man we are so screwed!
I'll be attending Omni grd schl on the 2nd in Tulsa.
