I agree. I am frustrated by this. It seems that any hotel that uses DirecTV and the PPV options it provides, have a limited number of channels. I have stayed at many places in Atlanta over the past 6 months and the TV lineup varies. The worst was the Hilton Garden Inn Perimeter with about 9 channels. The best was the Crowne Plaza Ravinia (belive it or not!) with about 60-70.
I have recently been staying at the North Central Atlanta Marriott and they have actually upgraded the system (or paid more to DirecTV) and we now have History, A&E, Discovery, Travel, HBO Family and ESPN2 in addition to the usual channels.
