We usually limit those to previous participants only, in that case iv found them to be great. Allows you to reconnect with the space and lessons for a night and get recentered on the healing. I usually don't recommend them for new people as the multi nights are better for working though the initial resistances and fear as your still learning to surrender and trust the experience but for those a little more seasoned it can be a great way to further your healing journey get what you need.
