We are due to sail next week and booked the Premier rate before the price/benefits changed. I was wondering if anyone has been in a similar position to us and knew whether we will be able to get any of the new benefits (e.g priority seating) or will it be restricted to the benefits listed at the time we signed up for it. Is there anything we will be eligible for that new premier customers cannot get? Thanks in advance for any help or advice
