Royal Caribbean leadership recently returned from visits to St. Thomas and San Juan and will be visiting St. Maarten on Wednesday. We continue to be impressed with the progress the islands are making to rebuild, and are excited to announce our return to St. Thomas with the Adventure of the Seas on November 10. In the next few weeks, working in conjunction with the local governments, we will announce the specific dates in November for our return to San Juan and St. Maarten.

We anticipate no further changes to our scheduled calls in St. Thomas, San Juan and St. Maarten for sailings December 1, 2017 forward.
