Luckily or perhaps not I never have many RC's built up during my recent trips to worry about it, so I've not been disappointed to see them go.
When I stayed at Borgata in July I was told at check out my charges would be taken care of, only to find my credit card was charged. I guess I assumed the host would comp the charges but I was wrong. On the other hand I used my comp dollars to buy an awesome handbag that I love.... Well worth more than the credit card charge.
Sorry Rob you lost your RC's but don't worry, just charge your GR meal to your room and hopefully your host will take off the extra charge in September
