We read that they will try to reschedule, but provide a refund if unable. We did raft in the rain some, and heard some thunder. The lightening showed in the distance as we were finishing, so they did hurry off the river, but we were already done.
Was mostly nice when we went. Rained lightly for a few min. It rains so often up there, unless it's really bad I don't think they stop. Not sure about cancellation policy.
