Open Bookings as they are now called have very few limitations but it does depend on the rules of the country of booking. The main advantage, and why we get them, is to be able to have the LCV discount on a cruise we are not able to book onboard. They do not expire so apart from having to layout the deposit cost and the restriction on making changes after you have transferred the open booking to a confirmed booking there is nothing that really stops us using them.
They are ideal if you want to wait and see if prices drop, particularly for a far out saiing
Here are their terms, they are self explanatory
OPEN BOOKINGS: Adventurer guests will receive 4% savings, Explorer 5%, Discoverer 6%, Discoverer 7%, Discoverer Platinum 10% on their future cruise. First-time Azamara guests will receive 3% savings. An “Open Booking” does not guarantee stateroom or sailing availability or cruise price. An “Open Booking” has no expiration date. Once a ship and sail date are selected and booking details finalized, the “Onboard Booking Offer” will be applied to the booking. An “Open Booking” may be applied against an Azamara Individual or group booking, but is not valid on any other cruise line, including any other affiliates of Azamara Club Cruises. Deposit. A non-refundable deposit equal to 50% of the amount normally required must be paid in your country of residence, per person, and full name for each guest will be required at time of booking. The minimum deposits required for all “Open Bookings” are non-refundable. The deposit is not refundable at any time after it has been paid. Changes. After a ship and sail date is selected and booking details finalized, no changes may be made to the ship or sail date. Further payments. Payments on your “Open Booking” beyond the non-refundable deposit required shall be due in accordance with the Azamara Club Cruises payment schedule applicable in your country of residence. Visit your Cruise Sales Team onboard and/or visit the Azamara Club Cruises website in your country of residence for more details and full terms and conditions. Cancellations. At least one name on the original “Open Booking” must remain the same throughout the life of the booking. Changing the original name will be treated as a cancellation. If the guest cancels an “Open Booking” the cancellation terms applicable to your booking in your country of residence will apply. The guest may apply for a refund subject to the terms of Azamara’s standard cancellation policy, less the amount of the non-refundable deposit. GENERAL: These terms and conditions apply to new individual bookings made on or after January 15, 2018. The “Onboard Booking Offer” is available only to new individual Azamara Club Cruises bookings made on or after January 15, 2018 onboard an Azamara Club Cruises vessel. All amounts stated are in U.S. dollars. OBO is combinable with Azamara’s general marketplace offers, back-to-back savings and single supplement savings. OBO may not be combined with certain restricted fares such as, but not limited to, Interline, travel agent and travel agent rates, family & friends, employee rates, shareholder benefits or net rates and may not be used on chartered voyages. As we value our relationships with our travel partners, unless we are advised otherwise your CRUISE AGAIN booking will be attributed to the travel partner associated with your current cruise booking. However, if you wish to have your booking reflect an alternative arrangement, please inform the onboard CRUISE AGAIN team at the time of booking and a form will be provided for you to sign as your authorization. Individual bookings may be transferred into non-contracted groups and higher deposits may be required. Individual enrollment may be converted and applied to a group booking. For information on transferring your CRUISE AGAIN Onboard Booking into contracted or non-contracted group space, please contact your local Travel Professional or Azamara Club Cruises.
