I tend to wake up with the sun, no matter the time so I leave the drapes slightly open and use the dawn as my alarm clock. But that doesn't mean I ignore the hotel system. I am fairly tech savvy and try to check settings, but some hotel clock systems are unfathomable. If they're that bad, I suggest getting rid of them. I wouldn't mind a simple alarm clock that uses light and moderate sound. I don't need a radio or music... in fact, find it annoying because people in other rooms can be inconsiderate. I learned the hard way that a front desk wake up phone call can't be relied on. I missed an early flight because a call system failed. Nowadays I set my phone alarm, but also a back up.
