For better or worse, we just see alcohol differently to gambling and other vices and very few people are scandalised by the idea of children being around adults having an alcoholic drink. A lot of kids see their parents drinking (not getting drunk, hopefully!) on a pretty regular basis anyway. People taking their kids along to watch them gamble does feel more seedy than that. Whether that's logical or not, it would make me more uncomfortable and change the feel of the parks for me so I wouldn't like it. I'm also not thrilled they're getting into gambling apps.
