I am booked for May 9. Paid in full. This is a bait and switch policy. I am a dual American French passport holder. My husband and I both vaccinated. I would feel like a hostage. THIS POLICY will discourage new bookings and encourage cancellations. Would or might reconsider if the excursions were free or if they offered free drinks ! Lol ! Otherwise I could cancel get my money back and use my flights to do my own thing. I hope with time; this policy will be readdressed and changed. They will sail with VERY few people.
