I agree with Felicity. I don't think it's hypocritical. Someone may choose not to have a TV in their home for several reasons - Just because there isn't a TV in the home doesn't mean the individual sees a TV as wrong. Life is busy - some may find a better use for their time (outdoor activities, work, volunteering in the community). Even so, if they're at a hotel and have time to waste, there isn't anything 'wrong' with watching TV. Personally, having a TV would be unnecessary expense. I don't have much time on my hands as it is.
I think it would confuse children the most if it was labelled as a sin or wrong - if it's just a preference - like Felicity said, I think they'll be fine.
