Please take time to carefully read through our Payment, Deposit and Withdrawal/Transfer Policies stated below.

Deposit Policy

Group size: A $100 per person, non-refundable deposit applies to your original registered group size as well as any additions to your group thereafter. This per person non-refundable deposit increases to 50% of the participant fees once you enter 60 days prior to your service and learning trip. We understand that it can be difficult to project your final group size at the time of registration. Therefore we suggest that you provide a conservative estimate of your group size when you register. As your team develops, you may increase your numbers by calling us at 509-930-7558 providing space is available. Service and learning trips are filled on a first-come, first serve basis.

Payment

Payment is acceptable by check only: Check should be made out to MENDING WINGS (this is the umbrella ministry of which S.L.A.M. is a part) and you can mail your check to:

Slam Trips Financial Office
P.O. Box 324
Wapato, WA 98951

Payment is expected within 14 days of receiving your electronic invoice.

Withdrawal & Transfer Policy

The Mending Wings staff invests a great deal into offering community based, locally led S.L.A.M. trips that allow for your group to not only observe the Yakama Culture but to be invited into relationship built around learning and mutual respect. Planning and preparing for your group’s arrival entails the intentional investment of funds into covering the up-front fees necessary to secure staff, local leaders and teachers, housing and shower facilities, and cultural immersion elements.
