@Adrienne174 Nothing wrong with having a clock, but almost everyone these days has a cell phone they check the time and set an alarm on. The only time I ever use an alarm clock is if I have an early morning flight to catch and have to get up at some ungodly hour. I'll set my phone alarm and also the clock, because I'm nervous about sleeping through the alarm. So maybe there's other travelers like that who'd appreciate it.
And I know some people like white noise machines, but to me, they're just another form of noise. However, if you live where there is traffic or other noise, it certainly wouldn't hurt to offer it.
