Got this email this afternoon. Looks like they have lifted this restriction now:
It’s important to us to be as communicative as possible during this very fluid novel coronavirus situation. Over the last few weeks, governments around the world have been restricting travel for Chinese, Hong Kong, and Macau passport holders – often times with little advance notice. As a result of these restrictions, last week we decided to add a similar policy to our travel regulation, to avoid disruption to impacted guests’ vacations.
Now that governmental restrictions have been clarified, we have made a change to our travel regulation. We’re happy to share that effective immediately, passport holders from China, Hong Kong, and Macau will be able to sail with us.
If you had to cancel your upcoming reservation due to this travel regulation and you’d like to reinstate your reservation, please contact your Travel Advisor, contact us at 1-800-256-6649, or visit www.RoyalCaribbean.com/contactus for your local Royal Caribbean International office phone number. Please know, we can help reinstate your reservation and your rate will be protected. We are terribly sorry for the impact to your vacation and the inconvenience.
