Due to Covid we didn't have a retreat in 2020 or 2021. In 2022 we had a short one but the diocese does require a retreat. Below is a retreat schedule from St Francis De Sales Confirmation Retreat in 2019.
I was thinking we could shoot for 11 - 4 and end with confession and Saturday Vigil mass. We would eat pizza around @ 1 PM.
The later in March the better it seems to me because it is warmer but that could make it more difficult for folks to attend. I want to be as compliant as I can be with your schedules. I realize how difficult scheduling everything can get.
