It shouldnt matter if you get your money back or not. What should matter is if you feel your time and money was worth it. You have some fun,make some new friends. You can even win some money depending on the races(like Mahomet) or if you place a bet with a friend. Is it enough to brag about? No,maybe enough to pay for the weekend and thats it.

But if your enjoying yourself with friends and other good people(or even your family). Then to me,that is money well spent.
