A friend had been to a prior retreat and mentioned the upcoming retreat; Growing In Grace Through The Rosary. My friend is a convert to Catholicism and thought through this retreat he might learn about the origin of the rosary, why Catholics pray the rosary, and the benefits of doing so. Or, something of that nature. Although the content wasn't exactly what we had anticipated, the retreat was a very pleasant experience.
Pros: Beautiful Music
Cons: Ensure You Know the content of your retreat topic
