I haven't traveled for bit either, in my last role it was a $125 per diem (which seemed extremely fair at the time). If you hosted a lunch the senior member in attendance had to be the one covering. I once used my corp amex to pay for my boss's lunch and it was a huge pain to resolve.

We used an expense website and had to turn in/scan itemized receipts in order to get our amex balances paid.

I think almost $300 for a day as stated above is a pretty big outing and you are probably reimbursing for alcohol... Which, my last company would reimburse if you had a beer with dinner. But beyond that I would never put more than one on the company card.
