Overnight Retreat Groups are required to purchase their meal plan from Refreshing Mountain, since there are no cooking facilities available for guest groups to rent. Additionally, groups must keep a consistent meal schedule (i.e. breakfast, lunch, and dinner) from the start of the retreat to the end of the retreat (i.e. no skipping meals).
Guests that are staying in Tents or Cabins generally have the option to provide their own food, provided that the total group size is less than 20 people.  For any overnight retreats with 20+ persons, a meal plan from Refreshing Mountain will be included in your quote for the event.
