How Many Nights?
Day trips can be a great place to start to get your feet wet. Bringing retreat goers is comparable to bringing kindergarteners on a field trip. Be sure to bring a first aid kit, extra snacks, and yoga mats for folks that may have forgotten them.
Overnight stays can be a wonderful experience, but also requires you to bring your A game! If choosing a long weekend, consider offering day passes for folks that cannot commit to an entire weekend.
M's Tip: Providing programming for an entire weekend can be demanding, so I always bring an intern (at no charge) to lend a hand. This is invaluable experience for them and an extra set of hands for you!
