Please notify Sea Base immediately if your unit intends to cancel. Early notification may allow Sea Base to rebook your canceled adventure. If Sea Base rebooks the adventure, all fees except for the original $250 reservation fee will be returned to your unit. Sea Base will not refund any fees to your unit if the adventure is not rebooked. Sea Base does not refund crews for canceled flights or ground transportation. Sea Base strongly recommends trip insurance.

Crews are responsible to know and adhere to the payment schedule. Failure to submit on-time payment will result in cancellation.

Disclaimer: BSA National High Adventure Bases set baseline pricing 12-24 months prior to attendance. Additional fuel, food, utilities or other surcharges may be required based on economic conditions, increased costs, and other factors.

If any such price change is implemented, the primary reservation contact will be notified directly and a notice will be published to the registration page for affected adventures.
