The conferences at retreats can vary, but many are focused on the theme of the retreat.
What you show is a semi-directed retreat where conferences and sacraments are provided at a scheduled time.
It depends on the place the retreat is held.
I use to go on retreats with the Passionists, and it was a directed retreat. Retreats were their bread and butter.
Later, I started going on retreats at a Trappist Monastery. Their retreats are not directed and there is only one talk by the retreat master, and it’s optional. The schedule provided follows the monks daily schedule and retreatants are allowed to attend Mass and the Liturgy of the Hours with the monk.
In all, retreats are well worth it. If you feel God calling you to go on a retreat, do it !
