Probably not a natural first choice for families with young children or even older children you're hoping to retain some control over. This isn't for lack of trying by the tourist office, who publish a magazine especially for children (and called "Children" in case there's any doubt) and the Arlberg ski school's first rate children's program. The 'Kinderwelt' day-care accepts toilet-trained children from aged two-and-a-half at its slope-side location for half or full day bookings. For younger children, children who don't want to stay in the Kinderwelt, or for evenings, there is a baby sitter list available from the tourist office.
The Ski school proper takes children from age five years at its base up on the Gampen. However children from birth are supposed to pay 10 Euros (up to age eight) for the 'Snowman Ticket' which is valid all season (not that you're likely to be there all season...) It's a low price, but charging at all seems strange and rather mean for this age group, undermining 'positive vibes' being put out by the other initiatives mentioned above.
St Anton's pedestrianised centre is a basically safe environment. If you stay centrally you may find it noisy in to the small hours; further out and you have to get the ski bus or walk.
