Okay... so hypothetically speaking ( ), you are about to own your own consulting firm in less than a week.

Having not worked in a firm with a "reasonable" travel policy before, you are going to set out to write the policy for your firm. You will be a small shop with four to six folks max traveling on the company nickel and not spending a majority (more than 5%) of time in any one city. Your average traveler is on the road 30 to 40% of the time, typically for one to three night stays. Most (98%) of your clients are not-for-profit entities so they expect some reasonability to your expenses (the Four Seasons is out of the question but they don't expect you to stay at the Days Inn either, although that may be your only option in some towns you will travel to).

What would be your must have elements to your ideal travel policy?
