Royal Caribbean's Pre-Cruise Summer Sale is offering up to 30% off select pre-cruise purchases made via the Cruise Planner.
The three-day sale is available for guests on select sailings, and offers discounts on services, such as unlimited drink packages, internet packages and even some shore excursions and spa treatments. Offer applies to new purchases made June 17 - 19, 2017. Discount applies to beverage, internet, dining and spa packages on select sailings departing July 1 - December 15, 2017. Discount amount varies by amenity type.
The exact discount available will vary from sailing to sailing, but there appears to be a fair amount of discounts applied.
Based on the countdown clock, it appears this promotion ends at midnight on June 19, 2017.
To check what items are on sale for your sailing, log into the Cruise Planner on Royal Caribbean's web site to see any available offers.
If you have already prepurchased something on the Cruise Planner that is now less expensive, you should be able to cancel the purchase and then re-purchase the same service under this promotion.
