In my parish, the choices are Saturday evening and Sunday morning at 9. (It used to be 8 and 10, in which case we were 10 o’clockers, but with the new building we’re able to fit everyone and it’s much better community-wise to have just the two Masses). I’m a 9 o’clocker now.
When I lived in Syracuse, there were Masses on Saturday evening, Sunday am at 6, 9 and 12:30 (English), 10:30 (Polish) and 4pm (Latin). We were 9 o’clockers there, too. There were a few occasions in which I went to the 12:30, but I felt like it was really unbalancing my day (couldn’t really fast all the way from bedtime Saturday to after the 12:30 Mass).
