I'm sure coaches' meet fees vary by area, gym, booster club, etc., but here's what we pay for each coach who attends a meet (we often take more than one coach to a meet when there are multiple levels competing at the same time or split sessions for one level):
1. transportation to the meet - normal mileage if he/she drives, or airfare, and car rental if its a fly away meet.
2. Per diem for food - varies by location but usually $30 - $40 per day
3. Hotel room
4. Session fees - $50 - $100 per session per coach depending on the meet
5. Incidental expenses
We try to have coaches share a room or car ride wherever possible. We have found that if we are fair with our coaches regarding their expenses, they will be reasonable in what they turn in. It has worked out well for all concerned.
