Granted, I don't have kids. But who really cares about the cable channels when staying at a hotel? Usually near the bottom of my concerns when traveling.
The only place we have stayed in a hotel with the kids was Disney World...and considering our TV at home is almost always on Disney or Disney Jr., we had very little need to see what else they offered. (Quite a bit, actually.) I think if we were to go somewhere non-Disney with the kids, we'd probably want to make sure they had at least something kid-friendly, or at least good wi-fi so the kids could watch on their iPads. But honestly, with kids as young as mine, time spent in a hotel room is minimal; as long as it's clean and there's a place for everyone to sleep, we're good.
