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.

Open Registration is a first come, first served opportunity. It is not a lottery. Reservation is immediate.
