We've booked a rental through a reputable bnb broker near Yosemite for early September and obviously the forest fires and the partial closing of Yosemite National Park now raise a lot of concerns. What should we prepare for and discuss with the broker about the possibility of not having an enjoyable visit with nature in the Park. Cancellation clauses, rebate, refund? We're looking ahead and hope we don't have to do anything other than enjoy Ansel Adams land. Thanks in advance!
