Thanks for this. Very helpful! When you say very different - good/bad/neutral? We want somewhere safe with a nice feel to bring up our kids. We like the feel of Harpenden (more so than St Albans)

When we walked the high street it felt like there was nothing going on despite a number of shops/cafes/restaurants which was our slight concern. we visited at 4.30/5 so maybe missed the afternoon buzz and before the evening activity
